Skip to contents

Replaces the content of an existing file in Google Drive with the contents of a local file. It is also possible to update (or upload if not already present) the output (pdf or html) of the file specifying the path_output argument. In case of html files, if pagedown package and Chrome are available, users can decide to upload a pdf version of the html file.

Use with caution as tracked changes in the Google Drive file will be lost!

(experimental) logical value (default is TRUE) indicating whether to upload to Google Docs a rich document (i.e., important text that should not be changed is highlighted). See “Rich Text” in details section.

Rich Text (experimental)

The rich_text option (default is TRUE) allows to upload a rich document to Google Docs. Important text that should not be changed is highlighted. This includes, added instructions at the top of the document, placeholders hiding the code, header of the document (YAML header or LaTeX preamble), code chunks, and in-line code.

Default colour is opaque yellow. You can customize the colour specifying the rgb_color option in the rich_text_par argument. The rgb_color has to be a list with elements red, green, and blue. Each element has to be a numeric value between 0 and 1. See example below.


if (FALSE) {

# Change default color to opaque light-blue
update_file(file = "path-to/my-file", rich_text = TRUE,
            rich_text_par = list(rgb_color = list(red = 102/255,
                                                  green = 204/255,
                                                  blue = 255/255)))
