Works for me. When you get the file with download.file is it
identical to when you download it from a web browser? I can only think
its getting corrupted, or perhaps your download.file isn't going
through a proxy or something and you're actually saving a proxy error
Check the length of the saved file: file.info(dest) should help -
check the 'size' is what you expect. I get 17004 for that example.
