saving png images and X11

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.

 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
