[R] Saving R Graph to a file

[Robert Baer]

Some hints:
For pdf(), height and width are in inches, not pixels.  dev.off() is 
necessary after drawing the image for pdf(). The name for the file 
argument (file="c:/figure.xxx") is file not filename

hist(CO2[,5]) is more interesting

And yes,
?pdf
?postscript
?ping
