Problems with Downloading pdf file using R

Question

I would like to download a pdf file from the internet and save it in the local HD. After download, the pdf output file has lots of empty pages. What can I do to fix it?

Example:

require(XML)
url <- ('http://cran.r-project.org/doc/manuals/R-intro.pdf')
download.file(url, 'introductionToR.pdf')

Thanks in advance.

Answer 1

Try with wb-mode like this:

download.file(url, 'introductionToR.pdf', mode="wb").

For me it works that way.
