df_printer: data.frame automatic printing as a flextable

In flextable: Functions for Tabular Reporting

data.frame automatic printing as a flextable

Description

Create a summary from a data.frame as a flextable. This function is to be used in an R Markdown document.

To use that function, you must declare it in the part df_print of the 'YAML' header of your R Markdown document:

---
df_print: !expr function(x) flextable::df_printer(x)
---

We notice an unexpected behavior with bookdown. When using bookdown it is necessary to use use_df_printer() instead in a setup run chunk:

use_df_printer()

Usage

df_printer(dat, ...)

Arguments

dat	the data.frame
...	unused argument

Details

'knitr' chunk options are available to customize the output:

• ft_max_row: The number of rows to print. Default to 10.

• ft_split_colnames: Should the column names be split (with non alpha-numeric characters). Default to FALSE.

• ft_short_strings: Should the character column be shorten. Default to FALSE.

• ft_short_size: Maximum length of character column if ft_short_strings is TRUE. Default to 35.

• ft_short_suffix: Suffix to add when character values are shorten. Default to "...".

• ft_do_autofit: Use autofit() before rendering the table. Default to TRUE.

• ft_show_coltype: Show column types. Default to TRUE.

• ft_color_coltype: Color to use for column types. Default to "#999999".
