Save a list of plots to multipage PDF.

Usage

save_pdf(
  plots,
  output_file,
  width = NULL,
  height = NULL,
  make_thumbnail = FALSE,
  stop_on_error = FALSE
)

plots: A list of plots.
output_file: A character scalar: path to output PDF file. If file's directory doesn't exist, it will be created recursively.
width, height: A numeric scalar: default width and height of graphics region in inches. Defaults to 7.
make_thumbnail: A logical scalar: if TRUE, a PNG file will be created from the first plot in plots.
stop_on_error: A logical scalar: if TRUE, the function will stop when there is an error during the saving of the plot. Otherwise a dummy PDF/PNG thumbnail file with error description will be created instead.

A named list with the following items:

success: a logical scalar indicating whether the plot saving succeeded (TRUE) or not (FALSE).
error: a character scalar with error message if success is FALSE, NULL otherwise.
error_plot: a ggplot2 object with error plot if success is FALSE, NULL otherwise.
output_file: a character scalar, identical to output_file parameter.
thumbnail_file: a character scalar, path to thumbnail PNG file if make_thumbnail is TRUE, NULL otherwise.

Note that success of FALSE and the accompanying error message and plot are only possible when stop_on_error is FALSE.
