Dear all,

I encountered a problem in using the CDF file for Human Exon 1.0 ST
microarray. I downloaded exon.pmcdf_1.1.tar.gz from
http://xmap.picr.man.ac.uk/download/ and managed to install the package in
R, but when I typed "library(exon.pmcdf)" I got the following error report:

Error in library(exon.pmcdf) :
  'exon.pmcdf' is not a valid package -- installed < 2.0.0?

Does anybody have an idea what might be causing this problem?

Best regards,

 - Essi Lahti
