As per the affy DESCRIPTION file, affy depends on package Biobase.
There are various methods of acquiring the Biobase package:
- If you have R-1.7.0 for Windows you can select the "Install Packages
from Bioconductor" option under "Packages" pulldown.
- You can download directly from our website:

http://www.bioconductor.org/repository/release1.1/package/html/Biobase.html
or
http://www.bioconductor.org/repository/devel/package/html/Biobase.html

Depending on if you want the release1.1 or devel versions, respectively.

- You can use getBioC() (and if you had already used getBioC, I'm not sure
why you don't have Biobase):
