Hi, I faced problems in loading package "annotate" after opening a previuosly saved R session in which i made use of that package. > library(annotate) Error in mlistMetaName(f) : No way to associate a generic function with an object of class "NULL" Error in library(annotate) : .First.lib failed This happened using the stable release (included in BioConductor 1.1). Then i installed the developmental release for all the packages, deleted all the objects saved in the session and created new objects, but the problem appeared again once i opened the session and loaded library "annotate". Can anyone give me any help to fix this problem? Another question is about the function "read.affybatch" in package "affy" 1.2.2. It seems not to actually load any data from .cel files into result object. Looking through the source file it seems to miss instruction to do that. So, i added two lines from an old version of "read.affybatch", it worked and that's the "diff": 72a73 > intensity(conty)[,1]<-as.vector(intensity(cel)) 99a101 > intensity(conty)[,i]<-as.vector(intensity(cel)) I haven't seen any mail citing this problem so i wonder if that's right. I'm using R 1.6.2, Linux redhat 8.2, i686 architecture.

Hi, I found the answers by myself, but I think that may be useful to post them. The problem described below arises when you save an object with a name that is used as a class name in a library. Actually, when you quit R in such a situation you are advised that some package may not be opened.
