And what does any of this have to do with XQuartz? That is the
third-party X11 server/sub-system for OS X. Perhaps the quartz() device
was meant ....
For the sake of those reading the archives, can we have a much clearer
statement of the actual problem? There might be better solutions,
including quartz(type = "pdf') (which is closer to what 'Save As' from
the quartz() device does).

Hi Paul,
Rather than use XQuartz, avoid "printing" the image and use the
pdf()/def.off() commands. Here's an example that I think answers your
question:
for(i in 1:10){
x <- i*1:10
y <- sqrt(x)
pdf(paste("File",i,".pdf",sep=""))
plot(x,y, main = paste("Test Case",i),type = 'l')
dev.off()
}
Or, move pdf() before and dev.off() after the loop and make one big file with
all the graphs on different pages.

Note that the paste function gives you the file name within the pdf
function. Check out the ?pdf file to see how to change the width,
height, or file type.
If you are using ggplot2, ggsave can do similar things.
Does this help?

I am generating within a loop a large number of XQuartz images. I know that I
can use the Save As command to save each one individually. This is very time
consuming and tedious. Is it possible to save them automatically with a R
script command?
Thanks for any tip that one can offer.
Paul
