Dear r-helpers:

Any ideas how to avoid problem described below?
I am having the same problem when I run R remotly (not from cgi script);
somehow png device wants to talk to X11 and X11 complains...

Best regards,
Ryszard

error msg from batch R process (Linux/R-2.4.0) (executed on Apache server 
from cgi script):

Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, 
 :
        unable to start device PNG
In addition: Warning message:
unable to open connection to X11 display ''
Execution halted
