[R] Can't install new packages

[John Shonder]

I am using R 1.7.0 under unix, installed on Mac OS X
via fink. I wanted to install the date package, and
used the following command:

install.packages(date)

It sure looked like it was going to work:

Error in unique.default(pkgs) : unique() applies only
to vectors

What is this "Error in unique.default(pkgs)? By the
way I ran R under the "sudo" command, so things could
certainly be written to other directories if
necessary.

I appreciate any help. Thanks.
