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
