saving png images and X11
Hi Bogdan, If we take the error message seriously, it may be that the initial X11 image was never displayed. When this very suspicious black box function tried to transfer the image to a PNG file, it wasn't there or the function couldn't find it. Jim

Dear all, I am using a R package that renders the png images. As I am running the command below in a script, I would like to avoid the error below and still be able to save the images. How shall I do it ?
ChIPQCreport(SAMPLE, + reportName = paste(ENTRY, "ChIPQC", sep="."), + reportFolder = paste(ENTRY, "ChIPQCreport", sep="."))
Saving 7 x 7 in image
Error in png_dev(..., res = dpi, units = "in") : X11 is not available
Shall I add the option :
options(bitmapType='cairo')
the png images are skipped and not saved on the disk. Thanks a lot,
Bogdan
