Hi, I have a batch routine that does PCA on a series of files and saves the results as a csv file, and the respective graphs as pdf and jpg. While pdf's are fine, jpg files have a light grey background does not matter what color i set the bg param. I am running this on a PC with 4 GB RAM - if this makes any difference. My command is as follows: dev.print(jpeg, file=filejpg, width=1024, height=768, quality = 100, bg = "white") I would appreciate if you have any explanations, and yes, i did read the help files this time ;-))) Thanks, Monica _________________________________________________________________ [[trailing spam removed]] [[alternative HTML version deleted]]
