R/src/base/R-0.50-a4.tgz: gzip compressed data, deflated, last modified: Tue Sep

This just shows that it is gzip'd. When you run gunzip on it the file
that is created is a "tar" file. The .tgz extension came from people
getting tired of writing a .tar.gz extension.
If you have the GNU version of tar, you can expand the source
directory tree with
tar zxf R-0.5-a4.tgz
Otherwise you have to use a two-step method of gunzip'ing it first
then running tar on the result. That is
gunzip R-0.50-a4.tgz
tar xf R-0.50-a4.tar
A third alternative is
gzip -d -c R-0.50-a4.tgz | tar xf -
