Maura, unz() is insisting that you give the "filename" argument,
which, according to '?unz', is:
filename: a filename within a zip file.
This means that you would first need to know the name[s] of the
file[s] archived in the .zip file, as far as I can see.
So, in that case, a first step would be to download the .zip
file anyway, to your local system, and then, in whatever way is
appropriate for your system ("unzip -l ...." in Linux), find
out what the files in it are called.
But once you have got that far, you may prefer to handle the .zip
file outside of R ...
Hoping this helps,
Ted.
