[BioC] question about ath1121501cdf package

[Wenlei Liu]

Dear Sir/Madam,

I'm a researcher at Penn State College of Medicine. I'm trying to use the R package 'affy' to analyze some affymetrix data. When I tried to view the data after loading it, I got the following error message:

AffyBatch object
size of arrays=712x712 features (15846 kb)
Error in .local(object, ...) : Information about probe locations for ATH1-121501  could not be found.
Try downloading the ath1121501cdf package from
http://www.bioconductor.org/data/cdfenvs/cdfenvs.html
Error in inherits(cdf.env, "try-error") : Object "cdf.env" not found

I went to the website and downloaded a package by clicking the "Win32" link next to "ath1121501cdf". After I installed the package, I got the same error message as before. The file I downloaded is "agcdf_1.3.2.zip". It is the same file as the agcdf package. I mean if you click the "Win32" link next to "agcdf", you will find the same file. Is this a error? Where is the ath1121501cdf package?

Thanks a lot for your time. Your feedback will be highly appreciated.

Sincerely yours,

Wenlei
