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 own fix was
simple, adding an extra parameter zipdir (without default), and within
the function change
tmpd <- tempdir()
to
tmpd = ifelse(missing(zipdir),tempdir(),zipdir)
This modification could maybe be useful also for other users, unless
there are some problems I am not aware of?
I won't comment on the value of the extra parameter, but the
implementation would be simpler if you set the default for zipdir to
tempdir(), and then just used zipdir in place of tmpd throughout.
