[R] trellis plot problem with R-1.9.0-1

[Stephan Moratti]

I tried following commands:

amp~time|subject/trial   #this was the grouping structure of the data


plot(dip,inner=~condition,layout=c(2,2))

after the plot command I obtained this error message:

Error in if(!any(cond.max.level - cond.current.level <0)&&(row-1)* :   
missing value where TRUE/FALSE needed

This error only occured in compination with "layout". It was no problem to 
plot all subjects on one page. Further, this error did not occur using older 
version of R (1.8 or 1.7). Did somebody encounter similar problems ?
