Wide summary table

This function is similar to tbl_summary(), but places summary statistics wide, in separate columns. All included variables must be of the same summary type, e.g. all continuous summaries or all categorical summaries (which encompasses dichotomous variables).

Usage

tbl_wide_summary(
  data,
  label = NULL,
  statistic = switch(type[[1]], continuous = c("{median}", "{p25}, {p75}"), c("{n}",
    "{p}%")),
  digits = NULL,
  type = NULL,
  value = NULL,
  sort = all_categorical(FALSE) ~ "alphanumeric",
  include = everything()
)

Arguments

data

(data.frame)
A data frame.

label

(formula-list-selector)
Used to override default labels in summary table, e.g. list(age = "Age, years"). The default for each variable is the column label attribute, attr(., 'label'). If no label has been set, the column name is used.

statistic

(character)
character vector of the statistics to present. Each element of the vector will result in a column in the summary table. Default is c("{median}", "{p25}, {p75}") for continuous summaries, and c("{n}", "{p}%") for categorical/dichotomous summaries

digits

(formula-list-selector)
Specifies how summary statistics are rounded. Values may be either integer(s) or function(s). If not specified, default formatting is assigned via assign_summary_digits(). See below for details.

type

(formula-list-selector)
Specifies the summary type. Accepted value are c("continuous", "continuous2", "categorical", "dichotomous"). If not specified, default type is assigned via assign_summary_type(). See below for details.

value

(formula-list-selector)
Specifies the level of a variable to display on a single row. The gtsummary type selectors, e.g. all_dichotomous(), cannot be used with this argument. Default is NULL. See below for details.

sort

(formula-list-selector)
Specifies sorting to perform for categorical variables. Values must be one of c("alphanumeric", "frequency"). Default is all_categorical(FALSE) ~ "alphanumeric".

include

(tidy-select)
Variables to include in the summary table. Default is everything().

Value

a gtsummary table of class 'tbl_wide_summary'
