I have 8 cofactors possibly affecting one and only one variable. I make conditional histograms:
<-pdf(file="tst3.pdf",paper="special",width=36,height=36) <-histogram(~Oversized|dat$c1*dat$c2*dat$c5*dat$c6*dat$c7*dat$c8*dat$c9*dat$c10,nint=21,layout=c(32,8),data=dat,type="count") <-dev.off() This works (compliments to R developers!) but it does generate a large plot with many panels being 'empty', e.g. that combination of factors c1..c10 never occurs in this data set. Is there a way to autmatically drop those empty panels? I looked at the docs: there is a drop.unused.levels parameter for trellis graphs but the docs says it is default true. I checked but could not make much sense out of the list of possibilties. Thanks!
