Works for me on Fedora 11 with the font packages mentioned in R
Installation and Admin manual.

plot(1:10, ylab = expression(delta*t))


If your question is rather why doesn't the "δ" glyph you enter at the
keyboard show up in the plot, I'm afraid I can't help. Perhaps something
to do with UTF-8 and locales and the available symbol set on the device
you are plotting on, but you'll need to provide more information (of the
sort requested in the posting guide) on your system and set-up.
