I'm trying to use mtext to create a main title over multiple plots. Below is
a simple self-contained example and my sessionInfo (I should note I've also
tried this with R-2.8.1 with the same results). When I execute the code
chunk below, I get the plots, but no title. I've tried this using the screen
driver, pdf, and postscript. I've used different sizes of paper. I suspect I
am making an elementary error but searching the help files and help archives
hasn't provided me an answer.
Thanks for any help, Mark
