Hello everyone,  

Can anyone give me some hint/suggestion for unzipping a file in R? The help file for "zip.file.extract" function seems to be difficult to understand.  

For example, the name of my zip file is "refGene.txt.gz", which is located in "C:\Documents and Settings\Desktop\test1". I would like to unzip this file to the same directory.  

Here's the syntax from the help file,  

zip.file.extract(file, zipname = "R.zip", unzip = getOption("unzip"))  

What I should use for the "file" and the "zipname" arguments? I tried different ways, but none of them is working. Thank you!  

Best regards,
