as_flextable.tabular: Transform a 'tables::tabular' object into a flextable

In davidgohel/flextable: Functions for Tabular Reporting

Transform a 'tables::tabular' object into a flextable

Description

Produce a flextable from a 'tabular' object produced with function tables::tabular().

When as_flextable.tabular=TRUE, the first column is used as row separator acting as a row title. It can be formated with arguments fp_p (the formatting properties of the paragraph) and row_title that specifies the content and eventually formattings of the content.

Two hidden columns can be used for conditional formatting after the creation of the flextable (use only when spread_first_col=TRUE):

• The column .row_title that contains the title label

• The column .type that can contain the following values:

  • "one_row": Indicates that there is only one row for this group. In this case, the row is not expanded with a title above.

  • "list_title": Indicates a row that serves as a title for the data that are displayed after it.

  • "list_data": Indicates rows that follow a title and contain data to be displayed.

The result is paginated (see paginate()).

Usage

## S3 method for class 'tabular'
as_flextable(
  x,
  spread_first_col = FALSE,
  fp_p = fp_par(text.align = "center", padding.top = 4),
  row_title = as_paragraph(as_chunk(.row_title)),
  add_tab = FALSE,
  ...
)

Arguments

x	object produced by tables::tabular().
spread_first_col	if TRUE, first row is spread as a new line separator instead of being a column. This helps to reduce the width and allows for clear divisions.
fp_p	paragraph formatting properties associated with row titles, see fp_par().
row_title	a call to as_paragraph() - it will be applied to the row titles if any when spread_first_col=TRUE.
add_tab	adds a tab in front of "list_data" label lines (located in column .type).
...	unused argument
