Hi, >From the following pseudo-code (tweaked from another user): library(lattice) variable<-sample(rep(1:2,100)) individual<-rep(1:3, length(variable)) group<-rep(LETTERS[1:2],length(variable)/2) mydata<-data.frame(variable,individual,group) individual<-as.factor(individual) group<-as.factor(group) histogram(~variable|individual+group)
I get six panels, one for each of individuals 1-3 in group A and one for each of individuals 1-3 in group B . What I want is three panels, one for each individual, but with A and B paired in the same panel. I think the "groups="argument does this sort of superposition for other lattice functions, but is apparently unavailable for histogram(). Thanks very much for any help. ______________________________________________ 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.
