Render slides as PDF file.

Render slides as a PDF file. Requires a local installation of Chrome. If you set complex_slides = TRUE or partial_slides = TRUE, you will also need to install the chromote and pdftools packages.

Usage

to_pdf(
  from,
  to = NULL,
  complex_slides = FALSE,
  partial_slides = FALSE,
  delay = 1,
  keep_intermediates = NULL
)

Arguments

from

Path to an .Rmd, .qmd, .html file, or a URL. If from is a URL to slides on a website, you must provide the full URL ending in ".html".

to

The name of the output .pdf file. If NULL (the default) then the output filename will be based on filename for the from file. If a filename is provided, a path to the output file can also be provided.

complex_slides

For "complex" slides (e.g. slides with panelsets or other html widgets or advanced features), set complex_slides = TRUE. Defaults to FALSE. This will use the chromote package to iterate through the slides at a pace set by the delay argument. Requires a local installation of Chrome.

partial_slides

Should partial (continuation) slides be included in the output? If FALSE, the default, only the complete slide is included in the PDF.

delay

Seconds of delay between advancing to and printing a new slide. Only used if complex_slides = TRUE or partial_slides = TRUE.

keep_intermediates

Should we keep the intermediate HTML file? Only relevant if the from file is an .Rmd file. Default is TRUE if the to file is written into the same directory as the from argument, otherwise the intermediate file isn't kept.

Value

Slides are rendered as a .pdf file.

Examples

with_example("slides.Rmd", requires_chrome = TRUE, {
    # Render pdf from Rmd, html, or direct URL
    to_pdf("slides.Rmd")
