Dear Sirs, How can I revert to an older limma version? Typing "install.packages("limma")" in R gives a list of mirrors. How can I install the version I want after I obtain and untar the file (e.g, limma_2.9.1.tar.gz)? I am running R 2.5.0 on a Linux machine (CentOS 5). When using limma it will not go past the read.maimages command. I get this error: Error in readGenericHeader(fullname, columns = columns, sep = sep) : Specified column headings not found in file In addition: Warning message: input string 1 is invalid in this locale in: grep(pattern, x, ignore.case, extended, value, fixed, useBytes) I was told by a colleague that this may be due to my limma version. I try to use limma 2.10.5 and he uses 2.9.1 Could this be the reason? Thanks in advance Maya
