[R] I need your help....

[James MacDonald]

This is a question for the Bioconductor listserv, not R-help. In
addition, all current versions of affy will automagically download and
install any cdfenvs that you may need, so there is no need to do this
manually. If anything, you may need to update your version of affy.

It's an Affymetrix thingie, so the BioC list would be the more obvious
place to ask. Notice that there are R data packages, e.g.

http://biowww.dfci.harvard.edu/~bioconductor/data/cdfenvs/Win32/mgu74av2cdf_0.1.zip


and (if I understand correctly) S-PLUS data libraries like

http://www.insightful.com/support/ArrayAnalyzer/DataLibs/CDFLibs/mgu74cv2cdf.zip


and I suspect they are not interchangeable even though both come in
.zip files.
