One option is to use GNU wget which you can configure and test outside of R.
Once you have it working -- and it should work as it AFAICR supports more
arcane proxy settings than R -- you set
options(download.file.method="wget")
in your Rprofile and you should be fine for all subsequent file operations.
This worked for me when I wrote and submitted the patch to download.file
which Brian Ripley then applied to the R sources. Also, this should work on
just about any operating system as wget has been ported to most.
