I'm trying to set up a lattice plot with two y-axes for each panel. (Yes, I know that multiple y-axes are generally a bad idea; the graph is for someone else and they want it that way.) I've used a custom yscale.component in xyplot to achieve this: myyscale.component <- function(...) { ans <- yscale.components.default(...) ans$right <- ans$left foo <- ans$right$labels$at ans$right$labels$labels <- as.character(10*foo) ans } xyplot(Sepal.Length ~ Petal.Length| Species, data = iris, scales = list(y=list(relation="free&q...

...RUE, text=LETTERS[1:4])) #to set a second y-axis with an other scale: # convert data to proper scale: inp3[which(inp3$group=="A"|inp3$group=="B"),"val"]<-inp3[which(inp3$group=="A"|inp3$group=="B"),"val"]*3 # set second y-axis myyscale.component <- function(...) { ans <- yscale.components.default(...) ans$right <- ans$left foo <- ans$right$labels$at ans$right$labels$labels <- as.character((0.3)*foo) ans } #plot with second y-axis. This does not work: xyplot(val~GF,groups= group, data=inp3,type="o...

How do you persuade lattice to draw tick marks on both the left and right side of the y-axis, when relation="free" in the scales component? #Ticks appear on both sides histogram(~height|voice.part, data=singer) ##Ticks only on left histogram(~height|voice.part, data=singer, scales=list(y=list(relation="free"))) Providing tck as a vector of length 2 doesn't seem to
