Convert gtsummary object to a flextable object — as_flex

Function converts a gtsummary object to a flextable object. A user can use this function if they wish to add customized formatting available via the flextable functions. The flextable output is particularly useful when combined with R markdown with Word output, since the gt package does not support Word.

Usage

as_flex_table(x, include = everything(), return_calls = FALSE, ...)

Arguments

x: (gtsummary)
An object of class "gtsummary"
include: Commands to include in output. Input may be a vector of quoted or unquoted names. tidyselect and gtsummary select helper functions are also accepted. Default is everything().
return_calls: Logical. Default is FALSE. If TRUE, the calls are returned as a list of expressions.
...: Not used

Value

A 'flextable' object

Details

The as_flex_table() function supports bold and italic markdown syntax in column headers and spanning headers ('**' and '_' only). Text wrapped in double stars ('**bold**') will be made bold, and text between single underscores ('_italic_') will be made italic. No other markdown syntax is supported and the double-star and underscore cannot be combined. To further style your table, you may convert the table to flextable with as_flex_table(), then utilize any of the flextable functions.
