In particular, the output of sessionInfo() sot that we know what OS and type of hardware you are running on. However, from the output you pasted, I will guess it is Linux. When you start R, what does capabilities() say? The installation log for WidgetTools is fairly clear in telling you that there is a problem with using R's tcltk package. So you will want to investigate that first. You might also consult the R FAQs. + seth -- Seth Falcon | Computational Biology | Fred Hutchinson Cancer Research Center http://bioconductor.org

Are you running from a terminal without X11? If connecting via ssh, can you use -X and see if that changes things? At this point, I will refer you to the R-help list as this is not a Bioconductor issue. + seth -- Seth Falcon | Computational Biology | Fred Hutchinson Cancer Research Center http://bioconductor.org
