I am running R scripts and..I have following errors : > library(tcltk,warn.conflicts = FALSE); Error in fun(...) : no display name and no $DISPLAY environment variable Error: .onLoad failed in loadNamespace Error in library(tcltk, warn.conflicts = FALSE) : package/namespace load failed > > library(affy,warn.conflicts = FALSE); > library(affyPLM,warn.conflicts = FALSE); > library(simpleaffy,warn.conflicts = FALSE); Creating a new generic function for "plot" in "simpleaffy" Welcome to 'simpleaffy' Produced by The Paterson Institute for Cancer Research and funded by CANCER RESEARCH UK. http://bioinformatics.picr.man.ac.uk/simpleaffy mailto: microarray@picr.man.ac.uk > .............code........ > abatch <- read.affybatch(filenames = my.filenames,phenoData = my.pheno); > abatch Error in cdfName(object) : No direct or inherited method for function "cdfName" for this call AffyBatch object size of arrays=712x712 features (15849 kb) cdf=HG-U133A (??? affyids) number of samples=4 Error in cdfName(object) : No direct or inherited method for function "cdfName" for this call In addition: Warning message: missing cdf environment ! in: show(structure(list(), exprs = structure(c(159.5, 14118.5, 192.5, Thank you all, Saurin

Hi, The Bioconductor list might not be the best place to report problems loading the tcltk package. Maybe R-help? Certainly the error about no $DISPLAY environment variable set seems pretty clear. Is there any reason why you can't set your DISPLAY or use an Xterm / SSH or whatever with automatic X11 forwarding?
