Has anyone already created the cdf environment for Affy's bovine chip? I 
only see a single thread in the archives regarding this the subject, it 
was sent on 02/10/05 and indicated that a version might be put up the 
next day. I am currently unable to find the package, have written to the 
author directly but the email bounced. Could someone please point me in 
the right direction if the package does exist?--

At this point you need to install the cdfenv. Unfortunately, this is a
bit more difficult to do than simply zipping things up and using the
menu. You have three choices here:

1.) Use make.cdf.env, which will make an environment that you can use
now, but will only exist in your current workspace. You can save the
workspace and use it again, but it isn't portable like a normal package
where anytime you open R, you can load it.

2.) Get the tools to make packages on windows

This is moderately tricky, but if you follow all the (semi-terse)
instructions _exactly_, you should be OK.

3.) Wait until tomorrow when I can build the env for you. I would
already have it on the BioC site, but I was under the impression that it
was the new binary format, and we don't yet have the ability to build
envs with the binary .cdf files.
