R help - Apr 2003 - Re: Unzip gz files in R under Windows

I tried zip.unpack to unzip a gz file under Windows and got "error 1 in 
extracting from zip file". Did I do something wrong or is there a better
way of
unziping a gz file in Windows? The gz file is fine as I could unzip it visually 
throught Windows. Thanks.

It's not a ZIP file though. Some popular Windows programs will unpack
many different compressed formats, but zip.unpack will only do the
true ZIP format. To unpack a .gz file you need the gunzip program (or
gzip with suitable option). Notice that R can read gz files using a
(surprise...) gzfile() connection.
