Well, is it true that they aren't gzip files? Can you unzip them
with gunzip? If not, then problem is not in R. You can also
look at the extension: if it is .gz or .tgz, they are at least
supposed to be gzip files.
My memory is that the INSTALL command will check to see whether
the file is zipped or not (but I can't find this documented right
now). If I'm correct, then the problem is that the files are not
gzip files although they are labeled as such. In that case the
problem might lie in how you downloaded them.
It could also be that they are really tar files. What happens if
you look at the file with more? If you can read anything, then
it is probably a tar file and you might be able to re-lable it.
You might try again by starting R and using the
function rather than R CMD INSTALL. This will probably choose
the right method of downloaing. In fact, I would try this first.
