They are in a separate annotation data package. Second, we do not maintain annotation data package for hgu95a. But we do have the package for hgu95av2. To get the LocusLink annotation for hgu95av2 you need to use the annotation data package. You may try: >library("reposTools") >install.packages2("hgu95av2") # add develOK = TRUE if you need the devel track >as.list(hgu95av2LOCUSID) > > >Also, I tried : > >> myids<-(hgu95aLOCUSID) >Error: Object "hgu95aLOCUSID" not found > > > >Could any one help me hgu95a and hgu95CDF are both the >same chip definition files.
