This worked perfectly, thank you!

(Sorry for the delay, was traveling and didn't get a chance to test it until now.)

> I couldn't see it until now (that I got your csv file) but you should not be qusoting the cex parameter. Also it should be `cex.main` rather than just `cex`. As explained in the filled.contour help page (which you clearly have read) the legend is really a second plot and you should be using the title function(as you clearly have figured out.) But the details and examples are in ?title .

You should have used a .txt extension so you mailer would not improperly label it as something other than MIME-text. Or you could have simply copied the output of dput() into your email.
