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.
That seems fairly unlikely to be a zip file; it looks like a gzip file, based on the extension. zip.file.extract is for zip archives. The closest equivalent in the gzip world is a .tar.gz file. I don't know if there is a built-in gunzip function, but you can call a system function using system().
see gzip in R.utils. admitedly, it's help page is quite informative, as opposed to that for zip.file.extract. vQ
