You did not mention your specs, but here's how I do it on my Win2K machine,
behind a firewall, behind a proxy.
1-
If you're behind a proxy, load R through a batch file that loads
internet2.dll. To do so, open a notepad document. Write:
PATH C:\Program Files\R\rw2010\bin
START Rgui --internet2
Save your file as "r.cmd" in your C:\Program Files\R\rw2010\bin directory
FYI, internet2.dll makes R access the internet the same way your internet
explorer does.
2-
Here's the code I use to download and extract a zip file from the net.
download.file("http://www.cftc.gov/files/dea/history/deacot2005.zip";,
"c:/tmp/monthly/deacot2005.zip",
"internal", quiet = FALSE, mode = "wb",cacheOK = TRUE)
unzipped<-zip.file.extract("c:/tmp/monthly/annual.txt", zipname =
"deacot2005.zip")
