[R] lattice xyplot() postscript (?) problem in R 2.0.0

[Gerrit Eichner]

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:
