[R] Trying to save a *.jpg file from a PHP system call

   This is my first time making a request so please feel free to school    me on how to improve on how to make an inquiry. I am running R-1.9.1    in UNIX via a PHP script with a system command to generate a *.jpg    image from a list created by a perl script. This R script runs fine    when run from a Unix command line or through a system command from    Perl. In my debug efforts I had PHP print out the last executed    command from R. The R script hangs on my jpeg(), touch(), and X11()    commands in the script. If I comment these out the rest of the script    will run through. I am running R under my html directory and I have    ensured all permissions are fully open. I also set Sys.putenv() to    the machine I am working on. Your constructive response will be    appreciated.

   Thanks
