The easiest way is to convert the CDF file into what amounts to a large
hash table. Use the package "makecdfenv", and in there, the function
make.cdf.package, for this (from the Bioconductor website, and for nicer
features, under the section "Developmental Packages").
Then install the package "testcdf", and try to run read.affybatch again.
Best regards
