R help - Mar 2005 - lattice xyplot() postscript (?) problem in R 2.0.0

Dear all,

I work with R Version 2.0.0 on
Machine hardware:   sun4u
OS version:         5.9
Processor type:     sparc
Hardware:           SUNW,Sun-Blade-1000

and I have a very simple data frame (called OR) with the following 
variables:
> sapply( OR, class)
         X        ci      FTyp
  "factor" "numeric"  "factor"

(In OR$ci there are some Inf-values. OR's complete contents are appended 
below.)

If I do
> library( lattice)
> xyplot( X ~ ci | FTyp, data= OR)
the requested trellis plot appears and everything is fine. BUT, if I want 
to produce this plot in a postscript file a very strange and reproducible 
error ocurs:
> postscript( "OR.ps")
> xyplot( X ~ ci | FTyp, data= OR)
Error in "[<-"(`*tmp*`, pos.heights[[nm]], value = numeric(0)) :
         nothing to replace with

This procedure -- applied to this very data frame -- did work fine 
previously, i.e., when I used R 1.9.1. (traceback() didn't help me 
tracking the problem further down.)
I have the impression that it fails since I've started using R 2.0.0. 
Could this be a version related problem? Any ideas?

Thanks for any help!

  Best regards  --  Gerrit

PS: Here are the contents of data frame OR:
> OR
    X     ci FTyp
1  a 0.0000    A
2  a 0.0000    A
3  a    Inf    A

a) You should try R-2.0.1 with a recent version of lattice (or help to 
try out and test R-devel). It works!

b) You want to use trellis.device("postscript", ...) rather than 
psotscript().

Thanks to Uwe Ligges! The problem seems to have been my fault. Using his 
advice b) was the solution for me (under R-2.0.0). (My use of postscript() 
must have been a relict from my migration from S-PLUS to R.)
