gtsummary 1.5.0 2021-10-16

New Functions

New Functionality

Other Updates

  • Added a help file detailing the formula list notation used throughout the {gtsummary} package. (#981)

  • Updates to tbl_regression() documentation. The model N is no longer reported by default, and removed that section from the help file. (#998)

  • Updates to make the internal df_stats objects consistent across various {gtsummary} objects. Added internal function df_stats_to_table_body that adds the numeric df_stats tibble to .$table_body. The formatting functions are also added for the new columns to .$table_styling$fmt_fun. This function is now used in inline_text.gtsummary() to prepare the returned statistics (#921)

  • Now using broom::tidy() to prepare the car::Anova() results. This will be more stable than the version originally written. (#898)

  • The function assert_package() now takes the minimum required version of the package from the DESCRIPTION file, and the function is now exported.

  • Now using broom::tidy() to prepare aov() test results in add_p.tbl_summary(), which adds additional columns to .$table_body() (#956)

  • Updated the README to include links to a recording of a gtsummary presentation and to the RStudio Education blog post.

  • Removed maturing lifecycle tag from README.

  • Updated deprecated function workflows::pull_workflow_fit(x) to workflows::extract_fit_parsnip(x).

Bug Fixes

Breaking Changes

  • Updated add_p.tbl_summary(test = . ~ "mcnemar.test", group = id) syntax to require the group= argument to align with the paired Wilcoxon rank-sum test and paired t-test syntax.

  • Deleted deprecated functions add_comparison(), add_global(), tab_style_bold_p(), tab_style_bold_labels(), tab_style_italicize_levels(), tab_style_italicize_labels(), tab_style_bold_levels().

  • The following deprecated arguments have been removed: tbl_summary(group=), as_gt(omit=).

  • The survival package has been moved from Imports to Suggests, and will no longer automatically be installed when {gtsummary} is installed. Additionally, survival::Surv() is no longer re-exported with the package.

gtsummary 1.4.2 2021-07-13

  • Update to the internals of tbl_stack() to better handle when two or more stacked tables are then stacked again (#906)

  • Updates to make tbl_svysummary() compatible with {survey} package updates in v4.1 (#930)

  • The as_hux_table() function previously stripped markdown old syntax from column headers and spanning headers. The output now uses markdown syntax in the headers by default utilizing huxtable::set_markdown() (#885)

  • Variables passed in the tbl_svysummary(by=) argument will now automatically be added to include=. (#925)

  • Bold and italic requests are now ignored for kableExtra output. These are carried out via markdown syntax, which is not supported by {kableExtra} (#917)

  • Bug fix for add_p.tbl_cross(pvalue_fun=); argument was being ignored.

  • Updated style_pvalue() to format p-values slightly larger than 1 and slightly lower than 0 (due to imprecise numeric storage). (#907)

  • Fix allowing for factor vectors to be passed in tbl_stack(group_header=). (#908)

  • Updated arguments y= and x= in tbl_uvregression() to allow for non-standard names (#912)

gtsummary 1.4.1 2021-05-19

gtsummary 1.4.0 2021-04-13

New Functions

New Functionality

  • Print infrastructure has been updated to allow for both row and column specification when formatting data or table styling. The x$table_header object has been replaced with a more general x$table_styling. Review the updated vignette "gtsummary_definition.Rmd" for details. The x$table_body is no longer grouped after tbl_stack(); rather, the grouping variable is specified in gt::gt(groupname_col=)

  • tbl_summary() now accepts any class as input. Previously only non-date base classes were accepted. For non-base R classes, the summary type must be specified using tbl_summary(type=). The default summary statistic for dates/times is the minimum and maximum. (#488)

  • The add_stat() function may now return multiple columns of new statistics. Some arguments have been deprecated in the update. (#746)

  • tbl_uvregression() now accepts both data frames and survey design objects as input. (#742)

  • If the default tidy_fun = broom::tidy fails, parameters::model_parameters() attempts to tidy the model, if {parameters} is installed. (#854)

  • Added a custom tidier for mgcv::gam() models (tidy_gam()) and a method function (tbl_regression.gam()) that uses the new tidier by default. (#745)

  • Added default support for brmsfit model in tbl_regression() with new method function. (#751)

  • Functions modify_footnote() and modify_spanning_header() now include the text_interpret= argument indicating whether to use gt::md() or gt::html() to format text. Default is gt::md().

  • Added/updated functions add_n() and add_nevent() to work with tbl_regression and tbl_uvregression objects. Each function now has an argument to place Ns on the label or level rows. (#744)

  • Added The Quarterly Journal of Economics to theme_gtsummary_journal(). This journal theme will be updated again after the gt package updates cols_merge() with a rows argument and allows for line breaks within cell.

  • Korean and Icelandic language translations added for theme_gtsummary_language().

  • Ability to merge two or more columns with modify_table_styling(cols_merge_pattern=) argument.

  • Added theme element "pkgwide-fun:pre_conversion". The function specified here will be executed on the gtsummary object before it is printed or converted with the as_gt(), as_flex_table(), etc functions. (#773)

  • The modify_table_body(fun=) argument has been generalized to accept formula shortcut notation.

  • Added exploratory data analysis theme that shows more details by default, theme_gtsummary_eda().

Other Updates

  • Updatedtbl_merge() and tbl_stack() to capture the first source note and caption in the merged/stacked tables. Previously, any captions and source notes were lost.

  • Added messaging when table caption requested via modify_caption() for a gt table when using a version of gt that does not support captions.

  • Updates to the table gallery vignette reflecting changes in the package. (#775)

  • Improved error messaging when there is a problem constructing one of the univariate regression models in tbl_uvregression().

  • Added variable-specific formatting to add_difference(estimate_fun=) allowing a single table to show, for example, mean and rate differences that are formatted/rounded differently.

  • Improved handling and messaging to users when columns with "haven_labelled" class are passed to gtsummary functions. (#805)

  • Improved handling of ordered factors as the by= variable (#569, #540)

  • Removed {usethis} package dependency and replaced with {cli}. (#768)

  • Added the survey-adapted t-test to theme_gtsummary_mean_sd() for continuous variables in add_p.tbl_svysummary() (#758)

  • Allowing for tidyverse shortcut notation in tbl_survfit(estimate_fun=) specification, e.g. tbl_survfit(estimate_fun= ~style_sigfig(.x * 100)) (#761)

  • The JAMA journal theme has been updated to merge the coefficient and confidence interval columns.

  • Updated other inline_text() functions to wrap inline_text.gtsummary()

Bug Fixes

  • The label= argument for unstratified models was being ignored in tbl_survfit() (#842)

  • Preserve ordering for factor variables in tbl_survfit(). (#764)

  • Bug fix for spanning headers with kableExtra output. The spanning header was misplaced when the header text was sandwiched between two blank spanning headers.

  • Bug fix when displaying an unobserved level of a factor variable dichotomously in tbl_summary(). (#780)

  • Bug fix in add_p() where test name footnote was not being translated with theme_gtsummary_language().

Breaking Changes

  • tbl_survival() has moved from questioning to deprecated. This function maintains the old x$table_header format (instead of the more flexible x$table_styling). The "level_label" column was renamed to "groupname_col" and the x$table_body is no longer grouped with group_by(level_label)

  • The back-end implementation of add_stat_label(location = "row") has been updated. The function now merges columns "label" and "stat_label" instead of modifying the "label" column directly. This could be a breaking change if users had manually updated results, for example, from a tbl_regression() table to merge with tbl_summary() using tbl_merge()

  • The function add_stat_label() no longer auto-switches location = "column" requests to "row" in the presence of "continuous2" variables.

gtsummary 1.3.7 2021-02-26

  • No changes. Resubmitting to resolve CRAN quirk.

gtsummary 1.3.6 2021-01-08

New Functions

New Functionality

Other Updates

  • modify_header() has been updated so users may more easily access internal data while defining headers and so that it no longer adds its call to the gtsummary .$call_list (#719)

  • The default value for include= argument for the add_global_p.tbl_regression() and add_global_p.tbl_uvregression() methods have been made the same with include = everything(), and the help files for these methods have been brought together in a single file. (#721)

  • Introducing new package dependency {broom.helpers}

    • The tidying and preparation of tbl_regression() tables are now being performed by {broom.helpers} (#636, #607)

    • All select helper functions and the utility functions that make them possible, have been cleaned up and migrated to {broom.helpers}. (#648, #680)

    • Importing .generic_selector(), .select_to_varnames(), and .formula_list_to_named_list() from {broom.helpers}: this is a function that makes it easy to create selecting functions like all_continuous(). The internals allow for it to be used in {broom.helpers} and {gtsummary} seamlessly. (#680)

    • Theme element has been added for controlling the other tidy_plus_plus() arguments. (#692)

    • Variables that do not follow standard naming conventions are now parsed correctly and presented in the regression tables.

  • The tbl_regression() function is now an S3 method. The new interface allows for special handling of different model types using S3 methods: tbl_regression.default(), tbl_regression.lmer(), tbl_regression.glmer(), tbl_regression.survreg()

  • tbl_regression(add_estimate_to_reference_rows=) argument has been added. Also added to tbl_uvregression(). (#692)

  • Theme element for tbl_regression(add_estimate_to_reference_rows=) has been added. (#677)

  • Removed "Statistics presented:" and "Statistical tests performed:" prefixes from the tbl_summary() %>% add_p() footnotes.

  • The codebase powering add_p() and related methods has been refactored for better performance, organization, and customizability. (#622)

  • Added messaging to tbl_stack() to inform users that the attributes from the first table passed take precedent over the others’. (#699)

  • In the modfiy_*() functions, if users did not select any columns, they encountered an error. Now, if no columns are selected, instructions are printed for how to correctly select columns in a gtsummary table. Moreover, if no columns are selected, the gtsummary object is now returned unaltered. (#699)

  • The add_glance_source_note() function has been generalized so users may pass any glance function. Previously, broom::glance() was being used with no option to change it. (#699)

  • The ... arguments have been added to as_gt(). These dots are subsequently passed to gt::gt(...). (#701)

  • Multiple imputation models created with {mice}, and multinomial regression models created with {nnet} are now supported in tbl_regression() (#645)

  • Updates to add_global_p.tbl_regression() allowing for variable names with spaces and special characters (#682)

  • Added digits= argument to style_percent() (#690)

  • Users may now choose which tbl_regression() columns to report with a theme element. they can choose among the "estimate", "std.error", "statistic", "ci", "conf.low", "conf.high" and "p.value" (#637)

  • Allow users to include the reference value in tbl_regression() via a theme element

  • Users may change the symbol with a reference row symbol with a theme element. (#628)

Bug Fixes

  • Bug fix when a default statistic is set using themes for "continuous2" variables that has length larger than one

  • Bug fix when missing/non-missing percentages requested in add_n.tbl_summary()

Breaking Changes

  • The default test for 2-by-2 tables with expected cell counts has been updated from the chi-squared test with continuity correction to the original chi-squared test for add_p.tbl_summary() (#721)

  • Experimental function add_p.tbl_survfit(test.args=) in addition to accepting the formula list notation, also accepted a single string naming a test that was interpreted as everything() ~ "test_name". The single string is no longer accepted, and users must use the formula notation.

  • Removed theme element N_fun that was previously marked as questioning and likely to be removed from the package.

gtsummary 1.3.5 2020-09-29

New Functionality

Bug Fixes

  • Bug fix where estimate_fun= and pvalue_fun= were not being passed to tbl_regression() in tbl_uvregression()

  • There was an environments bug when evaluating the LHS of the formula inputs. In some complex situations, a stored character vector of column names could not properly evaluate (#604)

  • Fixed style_ratio() bug where there were rounding errors near one (#651)

  • Fixed style_sigfig() bug where there were rounding errors near thresholds (#638)

  • Adding the footnote from the stat columns describing the statistics presented to the overall column (#643)

Other Updates

  • Refresh of vignettes to use recently released functions (#649)

  • Moved the nevent column to after the N column when add_nevent() is called on a tbl_regression() object (#439)

  • gtsummary themes updates

    • Add theme_gtsummary_mean_sd() theme to report mean and SD by default and use t-tests and ANOVA in add_p() (#654)
    • Added first draft of the NEJM theme
    • Added the mid-point decimal separator for the Lancet theme

gtsummary 1.3.4 2020-08-27

  • Added a copy of tidyselect’s where() function to allow users to use predicate select helpers (#632)

  • Fixed tbl_cross() bug where function defaulted to 'column' when margin = NULL. Now it defaults to display no margins when NULL. (#624)

  • Changed default of tbl_survfit() missing argument from '\U2014' (em dash) to NULL (CRAN issue). Em dash is still displayed by default in tables but it is set later in function.

gtsummary 1.3.3 2020-08-11

New Functions

User-facing Updates

Internal Updates

  • Updated add_n() internals to be more efficient without recalculating statistics previously saved in tbl_summary()

  • {survival} package moved from Imports to Suggests

  • The add_overall() function is now a method function, and add_overall.tbl_summary and add_overall.tbl_svysummary added (#460).

  • Updated the variable labels for age and marker in the trial dataset.

  • Removed large *.gif files out of the package to reduce build size (#485)

Bug Fixes

  • Fixed bug where source note was not made smaller font size with compact theme when table was printed with {flextable} (#584)

  • Bug fix for tbl_summary() when a data frame contained an ordered factor column (#567)

  • Bug fix when only categorical summary statistics were requested for continuous variables in tbl_summary() and tbl_svysummary() (#528)

  • Bug fix when named list of {gtsummary} objects is passed to tbl_merge(x=) (#541)

  • Bug fix when for tbl_uvregression() when adjustment variables were included in formula = "{y} ~ {x} + age". The adjustment variables were being printed in the resulting table. (#555)

Breaking Changes

gtsummary 1.3.2 2020-06-14

  • Now returning all columns from broom::tidy() in .$table_body() (#516)

  • tbl_stack() now accepts a named list of gtsummary tables when using the group_header= argument (#524)

  • add_p.tbl_summary() bug fix for Wilcoxon rank-sum p-value calculation introduced in the last release (#525)

  • Delaying the release of as_huxtable() until the next {huxtable} release.

gtsummary 1.3.1 2020-06-02

New Functions

  • Introducing themes in {gtsummary}. Use the function set_gtsummary_theme() to set new themes, and review the themes vignette for details on setting and creating personalized themes. (#424)

  • New functions modify_footnote() and modify_spanning_header() give users control over table footnotes and spanning headers. (#464)

  • Introducing as_huxtable()! The function converts gtsummary objects to {huxtable} objects. {huxtable} supports indentation, footnotes, and spanning headers with Word, HTML, and PDF output. (#469)

  • New function add_stat()! Add a new column of any statistic to a tbl_summary() table (#495)

User-facing Updates

  • The following columns in tbl_summary() are now available to print for both continuous and categorical variables: total number of observations {N_obs}, number of missing observations {N_miss}, number of non-missing observations {N_nomiss}, proportion of missing observations {p_miss}, proportion of non-missing observations {p_nomiss}. (#473)

  • Improved appearance of default as_flextable() output (#499)

  • Added tbl_cross(margin=) argument to control which margins are shown in the output table. (#444)

  • The missing values are now included in the calculation of p-values in tbl_cross().

  • Messaging about statistical methods used has been added for add_global_p(), add_q(), and combine_terms(). (#471)

  • Added include= argument to tbl_summary(). The preferred syntax for p-values with correlated data is now tbl_summary(..., include = -group_var) %>% add_p(group = group_var). The group variable is now no longer removed from the table summary. (#477)

  • add_stat_label() function updated with location= and label= arguments to change the location of the statistic labels and to modify the text of the labels. location = "row" is now the default. (#467)

  • tbl_stack() function added the group_header= argument that groups the stacked tables and adds a horizontal header row between them. (#468)

  • Updated handling for interaction terms in tbl_regression(). Interaction terms may now be specified in the show_single_row= and label= arguments. (#451, #452)

Internal Updates

  • Improved error messaging when invalid statistics are requested in tbl_summary(statistic=) (#502)

  • All columns in as_tibble() are now styled and converted to character. Previously, styling was applied to most columns, but there were a few that relied on default printing for the type of underlying data. This was ok to rely on this default behavior for as_kable(), but with the introduction of as_flextable() we needed to style and format each column to character. Potential to break some code in edge cases. (#493)

  • Handling of passed custom p-value functions in add_p.tbl_summary() has been improved with more careful handling of the environments from which the functions were passed. Other related updates were also made:

    • Users may pass their custom p-value function as a quoted string or bare.
    • The basic functions for calculating p-values, such as t.test() can now be passed directly e.g. test = age ~ t.test. We now perform a check match check for functions passed. If it is passed, we replace it with our internal version that returns the p-value and assigns the test name.
    • If a user passes a custom function, and it’s not the proper form (i.e. a named list return object) AND the function returns a single numeric value, we assume that is the p-value and it’s added to the gtsummary table.
  • Updated the gtsummary core script, utils-gtsummary_core.R, to refer to all non-base R functions with the pkg:: prefix, so other packages that copy the file don’t need to import the same functions as {gtsummary} in the NAMESPACE. Now they just need to depend on the same packages. (#454)

Bug Fixes

  • Bug fix for inline_text.tbl_summary() when categorical variable contained levels with empty strings. There is still an issue if a user tries to select the empty string, however.

  • Fixed bug where some variables in tbl_cross() defaulted to dichotomous instead of showing as categorical (#506)

  • Bug fix when using a tbl_summary(by=) with missing observations in by= followed by add_overall()

  • Bug fix where values ">0.9" were incorrectly made bold using bold_p(). (#489)

  • Bug fix for as_flextable(). (#482)

    • Added a formatting function to all numeric columns to force conversion to character.
    • Spanning headers were being printed in alphabetical order! Update to preserve the ordering.

gtsummary 1.3.0 2020-04-17

New Functions

  • Introducing tbl_cross(), add_p.tbl_cross(), and inline_text.tbl_cross()! Easily construct cross tabulations of two variables.

  • Introducing tbl_survfit() and inline_text.tbl_survfit()! These will eventually replace tbl_survival(), which will no longer be encouraged. The new functions follow the structural guidelines of a {gtsummary} object and can be merged and stacked with any other {gtsummary} object (#280)

  • Introducing as_flextable()! The function converts gtsummary objects to {flextable} objects. {flextable} is a great option when using R markdown with Microsoft Word output. {flextable} supports indentation, footnotes, and spanning headers with Word, HTML, and PDF output.

  • Introducing as_kable_extra()! The function converts gtsummary objects to {kableExtra} objects. {kableExtra} supports indentation, footnotes, and spanning headers with HTML and PDF output. (#394)

User-facing Updates

  • Updated default print engine for {gtsummary} objects. {gt} is the default printer for the R console and R markdown documents with HTML output. PDF, RTF, and Word output default to using {kable} with a note referring users to a new vignette explaining why {gt} was not used. (#395, #396)

  • Updated add_p() custom p-value description to NOT require double escape characters for quotation marks (#361)

  • Created structure and enumerated list of unit tests each vetted model must pass, and added the tests (#383)

Internal Updates

  • Each gtsummary object has an associated .$table_header. The code needed to print a table with either gt or kable was previously a mix of information stored in the table_header, and code manually added to the gt_calls or kable_calls object. Now, all the information needed to print a table is stored in table_header. This has the advantage that any updates to the printing will now require an update to table_header only, and we no longer need to update the tibble, kable and gt calls. (#412, #414)

  • The {gt} package is now released on CRAN, and we’ve updated to depend on the CRAN version instead of the version on GitHub. This also resulted in significant updates throughout the documentation and code. For example, we no longer provide instructions for installing {gt}, or include internal checks if {gt} is installed. (#420)

  • Several functions have been made general, and may now be applied to any {gtsummary}-like object. Functions updated are add_q(), bold_p(), sort_p(), tbl_merge(), tbl_stack(), bold_labels(), bold_levels(), italicize_labels(), and italicize_levels(). (#434, #429, #373)

  • In tbl_regression() we previously printed the estimate, confidence interval, and p-value for all models. But some models don’t have associated methods for calculating the p-value or the confidence intervals. In this update, we now print the p-value if tidy() returns a "p.value" column. Similarly, the confidence interval is printed if tidy() returns "conf.low" and "conf.high" columns. (#391, #404)

Bug Fixes

  • Bug fix when data frame passed to tbl_summary() with a single column (#389)

  • In tbl_summary() passing an ordered factor in the by= argument no longer causes as error. (#453)

gtsummary 1.2.6 2020-02-13

  • Bug fix for random effects regression model where coefficients were not exponentiated when requested. Using broom.mixed::tidy() rather than broom::tidy() resolved issue.

gtsummary 1.2.5 2020-02-11


  • Updated documentation and README to improve readability, added more cross-linking across pages, added search terms to help users find our package, and added gif demonstrations (#340)

  • README images now build differently for website vs GitHub markdown to accommodate different output formats

Breaking changes

  • Removed deprecated fmt*_() and cols_label_summary() functions (#365)

  • Functions tbl_summary_() and add_p_() have been deprecated because the by= and group= arguments now accept strings (#250)


  • Package-wide update allowing arguments that accept variable names to accept bare/symbol inputs, character inputs, stored character inputs, and tidyselect helpers. When passing a single variable, the vars() function wrapper is no longer required. (#250)

    tbl_summary(trial, label = age ~ "NEW LABEL"))
    tbl_summary(trial, label = "age" ~ "NEW LABEL"))
    tbl_summary(trial, label = c("age", "trt") ~ "NEW LABEL"))
    tbl_summary(trial, label = c(age, trt) ~ "NEW LABEL"))
    tbl_summary(trial, label = vars(age, trt) ~ "NEW LABEL"))
    tbl_summary(trial, label = vars(everything(), -age, -trt) ~ "NEW LABEL"))
    age_column = "age"
    tbl_summary(trial, label = age_column ~ "NEW LABEL"))
    tbl_summary(trial, label = vars(age_column) ~ "NEW LABEL")
    purrr::map(c("trt", "grade"), ~tbl_summary(trial, by = .x))
  • Updated tbl_uvregression() to allow flexible tidyselect inputs and improved error messaging for arguments x and y (#249)

  • After the input updates in #250, the exclude= argument appearing in add_p(), tbl_regression(), tbl_uvregression(), as_gt(), as_kable(), and as_tibble() was redundant. The exclude= argument is now deprecated. Use include= instead, with tidyselect syntax. (#331)

  • Functions all_categorical(), all_dichotomous(), and all_continuous() may now be used in tbl_summary() argument type= (#256)

User-facing improvements

  • New pattern= argument in inline_text.tbl_summary(). Previously, we could only grab the entire cell from a tbl_summary() with inline_text(), and now we can get any single statistic reported (#254)

  • Improved messaging for users who use knitr::kable() to print gtsummary tables, and users who have not yet installed the {gt} package (#347)

  • New function combine_terms() allows users to combine multiple independent variables in a regression model into a single line after tbl_regression(). The single line does not report regression coefficients, rather a single p-value from the anova() function. (#310)

  • In the regression modeling functions tbl_regression() and tbl_uvregression(), the users are presented an informative error message when the tidier fails (e.g. broom::tidy()) alerting them to the location of the error so they may address the issue (#337, #338)

  • For each release of gtsummary, we now can make reference to the version of gt our release coincides with. The commit SHA for gt is now saved in an object called gt_sha, and the version of gt can be installed with remotes::install_github("rstudio/gt", ref = gt_sha) (#329)

  • Created “style” family of functions

  • Improved error messaging in tidyselect_to_list() (#300)

Other features and fixes

  • Updated class detection to use inherits(), and added secondary class of "gtsummary" to all objects. This allows users to create their own cobbled/custom gtsummary objects while utilizing the gtsummary print functions (#249)

  • tbl_summary() will now summarize columns of class difftime (#343)

  • Infrastructure update to the way styling/formatting functions are returned. Styling functions are now returned as a column in the .$table_header tibble. The update simplifies handling of these styling functions in tbl_merge() and tbl_stack(). (#298, #299)

  • Bug fix for tbl_summary() when variables were all NA (#344)

  • The data summary function add_p() now uses probabilities rather than counts to calculate expected cell counts to avoid an error when working with large data sets. (#341)

  • Cubic spline terms are now accurately matched to a variable name/term (#312)

  • Bug fix when non-standard evaluation arguments were passed in method.args= argument of tbl_uvregression() (#322)

  • Updates after the gt package deprecated gt::cells_data() in favor of gt::cells_body(). Check added to as_gt() ensuring a version of gt with gt::cells_body() in its NAMESPACE

  • Lowered minimum required version of R to v3.4 (#356)

  • Removed {broom.mixed} dependency as the {broom} package contained all necessary tidiers (#354)

gtsummary 1.2.4 2019-12-16

  • Bug fix in as_kable() where column header did not match statistics presented when certain levels of the by= variable are entirely missing in tbl_summary() (#304)

  • Updated the trial example data set "trt" variable to be "Drug A" and "Drug B" instead of "Placebo" and "Drug"

  • Improved messaging to users when an error or warning occurs while calculating a p-value in add_p(). Also, p-values are no longer omitted from output when a warning is encountered during their calculation (#283)

  • Added tidy_fun= argument to tbl_regression() and tbl_uvregression() allowing users to pass tidiers that are not in the {broom} and {broom.mixed} packages (#247)

gtsummary 1.2.3 2019-11-12

  • tbl_uvregression() now accepts an x= argument to build univariate regression models where the covariate x remains the same while models are built the with remaining variables as the outcome (#294)

  • Internal updates to the way {gt} is installed during CRAN checks.

  • Bug fix when stacking tbl_summary objects with calculated p-values.

gtsummary 1.2.2 2019-11-10

New Features

  • tbl_summary objects may be stacked and merged with tbl_stack() and tbl_merge() (#230, #255)

  • The add_n() function now reports additional statistics: total N, non-missing N, missing N, and their percentages. The missing = argument has been deprecated in favor of the statistic = argument. (#237)

gtsummary 1.0.0 Unreleased

First release since major re-factoring. The {gt} package is now used as the print engine to create all tables. Some function names have been modified to be more in line with other {gt} function calls, and additional functions have been added. The API for some functions has also been updated. Review documentation and vignettes for details.

Updated Function Names

    tbl_summary()       <-  fmt_table1()  
    tbl_regression()    <-  fmt_regression()  
    tbl_uvregression()  <-  fmt_uni_regression()  
    style_pvalue()      <-  fmt_pvalue()  
    style_percent       <-  fmt_percent()  
    style_ratio         <-  fmt_beta()  

New Functions
