Themes for gtsummary

Source: R/gtsummary_themes.R
gtsummary_themes.Rd

Additional themes for tables generated with gtsummary.

Usage

theme_gtsummary_prop_n(
  prop_stat = "{p}% ({n})",
  prop_digits = 1,
  mean_sd = FALSE,
  cont_digits = 1,
  set_theme = TRUE
)

theme_gtsummary_fisher_simulate_p(set_theme = TRUE)

theme_gtsummary_unweighted_n(
  n_unweighted_prefix = "",
  n_unweighted_suffix = " obs.",
  prop_digits = 1,
  mean_sd = FALSE,
  cont_digits = 1,
  overall_string = NULL,
  set_theme = TRUE
)

theme_gtsummary_bold_labels(set_theme = TRUE)

Arguments

prop_stat

(character)
Statistics to display for categorical variables (see gtsummary::tbl_summary()).

prop_digits

(non-negative integer)
Define the number of decimals to display for proportions.

mean_sd

(scalar logical)
Also, set default summary statistics to mean and standard deviation in gtsummary::tbl_summary(). Default is FALSE.

cont_digits

(non-negative integer)
Define the number of decimals to display for continuous variables.

set_theme

(scalar logical)
Logical indicating whether to set the theme. Default is TRUE. When FALSE the named list of theme elements is returned invisibly

n_unweighted_prefix, n_unweighted_suffix

(character)
Prefix and suffix displayed before and after the unweighted number of observations.

overall_string

(character)
Optional string to name the overall column.

Details

theme_gtsummary_prop_n() displays, by default, proportions before the number of observations (between brackets). This function cannot be used simultaneously with gtsummary::theme_gtsummary_mean_sd(), but you can use the mean_sd = TRUE option of theme_gtsummary_prop_n().

theme_gtsummary_fisher_simulate_p() modify the default test used for categorical variables by Fisher test, with computation of p-values by Monte Carlo simulation in larger than 2×2 tables.

theme_gtsummary_unweighted_n() modifies default values of tables returned by gtsummary::tbl_svysummary() and displays the unweighted number of observations instead of the weighted n.

theme_gtsummary_bold_labels() applies automatically gtsummary::bold_labels() to all tables generated with gtsummary.
