Subscribers, What is my mistake with the following example: library(lattice) testmatrix<-matrix(c(1,2,3,4,3,6,12,24),nrow=4,ncol=2) testylabels<-c('w1','x1','y1','z1') dotplot(testmatrix, scales=list(y=list(testylabels)), xlab=NULL) #testylabels not shown, instead 'D' 'C' 'B' 'A' Thanks in advance. --
