Hi all, I have some problems with the function 'make.cdf.package'. I installed Bioconductor, the affy package as well as the makecdfenv package. Then I tried to make an environment by using R> make.cdf.env(filename) or resp. R> make.cdf.package(filename) Both commands yield the error message: ============================================== Reading CDF file. Creating CDF environment Wait for about 228 dots.................................................................. ...................................................................... ...................................................................... ..... Error in make.cdf.package(filename) : couldn't find function "createPackage" ============================================== Does somebody have an idea why this error message occur resp. where I can find the function 'createPackage'? Thanx a lot, Tobias
