Small modification of zip.file.extract in utils?
Jon Olav Skoien · Oct 30, 2008 · r-devel

Dear list, I needed to extract a zip-archive, and found zip.file.extract in utils. My only problem was the use of tempdir(), since I wanted to permanently extract the archive at a fixed location for later use. My...
