In this case interaction would be conceptually more appropriate histogram(~Oversized | with(dat, interaction(c1, c2, c5, c6, c7, c8, c9, c10)), nint=21,layout=c(32,8),data=dat,type="count") but with(dat, paste(c1, c2, c5, c6, c7, c8, c9, c10, sep = ":")) should also work. -Deepayan > Thanks much! > Alex > > > > > <amvds <at> xs4all.nl> writes: > > > >> > >> 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? > >> > > > > Since there is little hope that you get a useful arrangement in the > > 2D-paper world, and neither in 4D relativistic space, I would > > suggest to make a new factor by pasting all cX factors, use that > > as the only grouping factor. > > > > Dieter > > > > ______________________________________________ > > R-help@r-project.org mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide > > http://www.R-project.org/posting-guide.html > > and provide commented, minimal, self-contained, reproducible code. > > > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
