Dear all, We have developed our own Affymetrix chip (Custom Express Array, PM-only with two species). I want to analyse the data with the limma package, but for that I need to built my own CDF package, probe package and built the filters to analyse one specie or another. I'm using the makeProbePackage available in the AnnotationDbi (for a R-2.13.0) but I got the following error message:
Error in rep(NA, max(pm1, mm1, pm2, mm2)) : invalid 'times' argument I already tried an old version of R-2.9.1 with a package matchprobes (that is no longer update for R-2.13.0) but the same error occurs. Does anyone knows how could I overcome this problem? Thank you very much for your attention.
