  Well, you dont say in what way it doesn't work. I get:

  However, if you add 'method="wget"' (and are running on a Unix box 
with wget installed) it works for me:

17:05:46 (319.71 KB/s) - `/tmp/RtmpHcpXlj/file643c9869' saved [832851]

  So I'm guessing its a problem with R's internal FTP client. Maybe it 
doesnt like underscores or minus signs... Speculation...
