Hi, Sohail.
Looks like you need to upgrade your R. Note that the affyio package
was
built under 2.3.0 and you are trying to load it into R 2.1.1, which is
a
year or two old. I'm not a windows user, but I'm venturing a guess
that
might be the issue.

Thanks Sean.
How can I upgrade R without having to install all the packages I have
already installed??

There have been threads in R-help that discuss this issue, so you
might
use RSiteSearch() to see if you can find one that you like. One
possibility is to install the new version of R, copy your library
directory over, and then run update.packages().
However, I don't see how this is any better (or faster) than simply
installing the new version of R and then installing all the packages
that you might want. This eliminates any problems you might encounter
with incompatible versions of packages.
Best,
Jim

If you use some of the command-line installation features, it isn't
really
that hard to install all the packages that you typically use in a few
lines.
My guess is that you don't actually use as many packages as you think
you
do, so I find that when I upgrade, I install a few very-often-used
packages
and then "install as I go" for the rest.
