Hi -

I have two questions concerning R 2.7. I'm running OSX 10.4.11. I  
have simply installed R 2.7 from the pre-compiled binary available on  
CRAN.

(1) Plot parameters from R 2.6 not compatible with R 2.7:  I have  
many scripts that plot manuscript figures and have invested many  
hours into formatting - particularly margins etc. However, when I run  
my scripts (which worked fine on R 2.6), the margins are bizarre,  
often plotting off the bottom of the quartz window, which doesn't  
make any sense in light of the mar and oma params I've specified. It  
is as though none of the plot parameters that worked for R 2.6 map  
onto R 2.7. I'm concerned by this. Does anyone have a simple  
explanation for this and/or a simple solution for a fix?

In Peter Dalgaard's posting, "CHANGES IN R VERSION 2.7.0", I find the  
following:

"The setting of the line spacing (par("cra")[2]) on the X11() and
         windows() devices is now comparable with postscript() etc, and
         roughly 20% smaller than before (it used to depend on the
         locale for X11).  (So is the pictex() device, now 20% larger.)
         This affects the margin size in plots, and should result in
         better-looking plots."

I don't see how this alone can explain the major problems I am  
having. I cannot get the bottom rows of some multi-panel plots to  
even fit in the quartz window.


(2) Missing fonts in R 2.7: Can't find the serif fonts, eg, family =  
'serif' argument causes problems and no text is displayed from mtext 
() or text(). I get the message:

In title(main = main, sub = sub, xlab = xlab, ylab = ylab,  ... :
   font "Times-Roman" could not be found

Any suggestions greatly appreciated.

Thanks,
Dan Rabosky
