[BioC] ReadAffy fails 64bit linux Error in .nextMethod(e1, e2) :

Thanks for following through, Bill.

The 'release' version of BioConductor packages have an even digit as the 
second part (the 'y' in x.y.z) of their version number, so if you're 
using a current R you probably meant 1.6.1.

For what it's worth, this is one reason why sessionInfo() can be so 
useful -- does the version of the package match the version of R and 
BioConductor? Assuming you're using the current released version of R, 
an easy way to check for yourself is to compare package versions 
reported by sessionInfo() with the version numbers on the pages linked 
from the 'Packages' link of http://bioconductor.org. And then to update 
packages, if necessary, using instructions on 
http://bioconductor.org/download.

Thanks again,

Martin
