生成R包手册时出错

Question

I having the following issue when trying to check a package using the command line. First I get this very general error message:

* checking PDF version of manual ... WARNING
LaTeX errors when creating PDF version.
This typically indicates Rd problems.
LaTeX errors found:
* checking PDF version of manual without hyperrefs or index … ERROR

Then, when I check Rdlatex log, I found the following complain:

Transcript written on Rd2.log.
Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet,  : 
  unable to run 'pdflatex' on 'Rd2.tex'
Error in running tools::texi2pdf()
You may want to clean up by 'rm -rf /var/folders/_q/_kj9kz0n0qq_gwkrv9qjvpxw0000gn/T//Rtmp7uzkmZ/Rd2pdf2a847787e63'

For some reason it didn't manage to run pdflatex though it is properly installed as the following testifies. Does anyone has a clue on how I can fix it?

system("pdflatex --version") pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2014) kpathsea version 6.2.0 Copyright 2014 Peter Breitenlohner (eTeX)/Han The Thanh (pdfTeX). There is NO warranty.

Very weirdly, running R CMD Rd2pdf man/ produces output.

I know this is a very old post, but for future readers - I had R CMD check and R CMD Rd2pdf fail because one of our collabs created an empty curly-braces block that was not escaped by roxygen and broke the laTeX render, .ie the \\dontrun{} below :

#' An example of breaking the R CMD Rd2pdf with unescaped curly braces.
#'
#' @param df A dataframe.
#' @return A dataframe.
#'
#' @examples
#' \dontrun{
#' }
#' @export
funcname <- function(df){
df
}
