Add model statistics returned from broom::glance(). Statistics can either be appended to the table (add_glance_table()), or added as a table source note (add_glance_source_note()).

add_glance_table(
  x,
  include = everything(),
  label = NULL,
  fmt_fun = NULL,
  glance_fun = NULL
)

add_glance_source_note(
  x,
  include = everything(),
  label = NULL,
  fmt_fun = NULL,
  glance_fun = NULL,
  text_interpret = c("md", "html"),
  sep1 = " = ",
  sep2 = "; "
)

Arguments

x

'tbl_regression' object

include

list of statistics to include in output. Must be column names of the tibble returned by broom::glance(). The include argument can also be used to specify the order the statistics appear in the table.

label

List of formulas specifying statistic labels, e.g. list(r.squared ~ "R2", p.value ~ "P")

fmt_fun

List of formulas where the LHS is a statistic and the RHS is a function to format/round the statistics. The default is to round the number of observations and degrees of freedom to the nearest integer, p-values are styled with style_pvalue() and the remaining statistics are styled with style_sigfig(x, digits = 3)

glance_fun

function that returns model statistics. Default is broom::glance() for most model obejcts, and broom::glance(mice::pool()) for MICE 'mira' models. Custom functions must return a single row tibble.

text_interpret

String indicates whether source note text will be interpreted with gt::md() or gt::html(). Must be "md" (default) or "html".

sep1

Separator between statistic name and statistic. Default is " = ", e.g. "R2 = 0.456"

sep2

Separator between statistics. Default is "; "

Value

gtsummary table

Default Labels

The following statistics have set default labels when printed. When there is no default, the column name from broom::glance() is printed.

Tips

When combining add_glance_table() with tbl_merge(), the ordering of the model terms and the glance statistics may become jumbled. To re-order the rows with glance statistics on bottom, use the script below:

tbl_merge(list(tbl1, tbl2)) %>%
  modify_table_body(~.x %>% arrange(row_type == "glance_statistic"))

Examples

# \donttest{
mod <- lm(age ~ marker + grade, trial) %>% tbl_regression()

# Example 1 ----------------------------------
add_glance_ex1 <-
  mod %>%
  add_glance_table(
    label = list(sigma ~ "\U03C3"),
    include = c(r.squared, AIC, sigma)
  )

# Example 2 ----------------------------------
add_glance_ex2 <-
  mod %>%
  add_glance_source_note(
    label = list(sigma ~ "\U03C3"),
    include = c(r.squared, AIC, sigma)
  )
# }
