[R] rotated and/or greek mtext in pictex()?

[Andrew Perrin]

Greetings-

I'm aware that there's no documentation for pictex available easily (that
is, without purchasing it).  I'm wondering if someone can help me with a
simple task. When generating a plot using pictex() from R, one of the
commands I use is

mtext("Dimension 2: L=xxxx", side=2, line=3)

when using X11(), this appears vertically along the Y axis; when using
pictex(), it shows up horizontally. So, question 1:
- Is there any way to rotate text in PicTeX?

Also: I'd like L to be $\lambda$ in the above example. Right now I'm
editing the pictex file by hand - is there a more elegant way to handle
it?

Thanks.
