Dear Biocondcutors, I used the arrayQualityMetrics package to generate quality control report. But I got this error: Error in X11(paste("png::", filename, sep = ""), width, height, pointsize unable to start device PNG my system information is uname -r 2.6.15-1.2054_FC5smp I think I installed the graphic library, rpm -qa libpng* libpng-1.2.8-2.2.1 libpng-devel-1.2.8-2.2.1 I installed the R from source and used default setting. How can I fix this problem? Thanks in advance Yisong [[alternative HTML version deleted]]

See ?capabilities how to check if you've got PNG support in R. Start a fresh R session. Try to generated some PNGs, see ?png. If either of these are not working for you, ask for help at the r-help list, because the problem unlikely to be related to BioC itself. Make sure to report your sessionInfo(). /Henrik On Mon, Aug 25, 2008 at 3:51 PM, Yisong Zhen <zhenyisong at="" gmail.com=""> wrote: > Dear Biocondcutors, > > I used the arrayQualityMetrics package to generate quality control report. > But I got this error: > Error in X11(paste("png::", filename, sep = ""), width, height, pointsize > unable to start device PNG > > my system information is > uname -r > 2.6.15-1.2054_FC5smp > > I think I installed the graphic library, > > rpm -qa libpng* > libpng-1.2.8-2.2.1 > libpng-devel-1.2.8-2.2.1 > > > I installed the R from source and used default setting. > > How can I fix this problem? > > Thanks in advance > > Yisong > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor >
