Yes, it has been solved and discussed in the R-help archives many times. The help(jpeg) page is pretty explicit too. One alternative is bitmap().
To use jpeg() under a Unix-alike you need to set up an X server that your R process can use. It's a bit hard to help you do that when you don't even mention your OS (I am inferring it is a Unix-alike), but you may be able to solve the permissions problem or you may be able to set by a server by something like Xvfb. In any case, it is not an R problem On Fri, 13 Jun 2003, michael watson (IAH-C) wrote: > I have seen a few posts to this list regarding problems accessing the > x11() device over cgi - namely, when trying to create a graphic using No, not the x11() device, but the jpeg() device.
