Well, see the posting guide and follow its advice -- 2.2.1 beta is
available so you are 3-epsilon versions out of date.
Beyond that, you have not told us your graphics device. I suspect this is
the X11() device and so an X11 font issue. Try
> options("X11fonts")
$X11fonts
[1] "-adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*"
[2] "-adobe-symbol-medium-r-*-*-%d-*-*-*-*-*-*-*"
and see if xlsfonts gives you anything sensible for the second pattern,
replacing %d by *.
