Hi Agens, Thanks for your kindly help! I downloaded the hexbin version 1.0.10 at the website you provided. I got the following error messages. > maQualityPlots(mraw) Loading required package: hexbin NOTA BENE: This is is an outdated version of the 'hexbin' package. It is known to have bugs ``by design''. *Strongly* consider using the new 'hexbin' version instead!! Error in devga(paste("png:", filename, sep = ""), width, height, pointsize, : unable to start device devga In addition: Warning message: Unable to open file `diagPlot.C:PROGRA~1/R/rw2000/library/marray/swirldata/swirl.1.png' for writing Thanks for your help!

Hi Yanqin, Could you precise which platform you are working on? This looks like you didn't install the device to generate png files. Did you try to generate images in another format instead? For example, you could try: maQualityPlots(mraw, dev="jpeg") Regards, Agnes -----Original Message----- From: Yanqin Yang [mailto:yanqin_yang@yahoo.com] Sent: Wednesday, December 01, 2004 9:29 AM To: bioconductor@stat.math.ethz.ch Subject: [BioC] Re: problem with hexbin Hi Agens, Thanks for your kindly help!
