filename

Hey,

I'm generating a .jpeg file for a web application passing parameters to 
R via cgi. R gets the parameters by using commandArgs, which are passed 
to a variable named j  and z

j<-commandArgs()[3]
z<-commandArgs()[4]

Later I want to use the characters strings of the argument which the 
variables are holding for my filename, e.g.:

jpeg(file="d:/data/images/jz.jpeg",...)
If j contains the name for the file,
jpeg(file=j, ...)
should work. I guess you do not have jpeg support if calling your script 
in non-interactive mode, because you need X11 active. See ?jpeg.

i tried to use paste and as.character, but neither worked out the way i 
want it to.

thanks for any advice, Lars Claussen
