R help - Jun 2004 - can't get text to appear over individual panels in multi-panel plot

I'm trying to learn how to create Trellis multi-panel plots, but I'm 
having some trouble reproducing the graphs shown in Venables & Ripley 
(2002) (e.g., Figs 4.14 & 4.15). Actually, everything looks fine except 
for the fact that I can't see any text above the individual panels.

I'm using R 1.9.0 for OS-X running on Mac OSX 10.3.3, and I'm drawing 
the graphs into the Quartz device.

Sorry for bothering the list with what is probably a trivial question, 
but I've run out of ideas...

Any help would be appreciated.


Cheers,
pjb

I don't have that edition, and it's difficult to guess without code, but
have you looked at the scripts that come with the MASS package ? They 
are supposed to reproduce the analysis done in the book (I'm assuming 
that the book you are referring to is in fact MASS). It might be as 
simple as replacing text() calls by ltext().

Hmm. I won't be able to help you then, let's hope someone else can.
