Hi, I am trying to create a dotplot where each panel shows levels vs. responses; the levels are sorted by responses but levels vary from one panel to another. However, I run into problems with controlling the y-limits and y-labels.
In particular, suppose I have a data frame rsp <- c(10,2,4,0,2,3) lvl <- factor(c("L1","L2","L3","L2","L3","L4"),levels=c("L1","L2","L3","L4")) cat <- factor(c("A","A","A","B","B","B"),levels=c("A","B")) xx <- data.frame(cat,lvl,rsp) print(xx) cat lvl rsp 1 A L1 10 2 A L2 2 3 A L3 4 4 B L2 0 5 B L3 2 6 B L4 3 I tried to follow the "Lattice ..." book and used dotplot(lvl~rsp|cat,data=xx,type=c("h","p"), panel=function(x,y,...){y1 <- reorder(y,x) y1 <- y1[,drop=TRUE] panel.dotplot(x,y1,...)}, prepanel=function(x,y){y1 <- reorder(y,x) y1 <- y1[,drop=TRUE] return(list(ylim=levels(y1)))}, layout=c(1,2)) However, the resulting has incorrect y-labels: Desired Plot Achieved Plot Panel B: Panel B: L4 L4 ----o L1 ----o L3 ---o L3 ---o L2 o L3 o panel A: Panel A: L4 L1 ----------o L1 ----------o L3 ----o L3 ----o L2 --o L2 --o It appears that the y-limits and y-labels specified by the pre-panel function are overwritten by something in dotplot. Can anybody suggest what I am doing incorrectly?
