Hi,
I tried to use savepng (library geneplotter) or jpeg (grDevices) to save the R output image in a file. When I run R in foreground, savepng saves the image in a file but when I run R in background (in a unix terminal shell), a file is created but with 0 byte. When the jpeg is used in R in bg or fg, a file is created with 0 byte. Why is the image not saved when I run the R in bg?

Regards,

carol
