Hi Dennis, thanks! No, this looks good to me, with equal-sized panels. I didn't realize there was such a similar post before - all my queries had retrieved questions about dropping categories in panels... but this is great - thank you.All the best!Stephen

From: djmu...@gmail.com To: obsessiv...@hotmail.com CC: r-help@r-project.org Hi: This looks to be a step in the right direction, but the resulting panels are all the same size. Perhaps you can build on it... # Solution based on an R-help post by Deepayan Sarkar: # http://tolstoy.newcastle.edu.au/R/e2/help/06/09/1579.html dotplot(A ~ B | C, data=dfr, scales=list(y=list(relation="free")), prepanel = function(x, y, ...) { # drop unused levels yy <- y[, drop = TRUE] # reset y-limits list(ylim = levels(yy), yat = sort(unique(as.numeric(yy)))) }, panel = function(x, y, ...) { # drop unused levels...again... yy <- y[, drop = TRUE] panel.dotplot(x, yy, ...) } ) HTH, Dennis On Tue, Aug 24, 2010 at 4:25 AM, Stephen T. <obsessiv...@hotmail.com> wrote: Hi list, I have a data set - something like this dfr <- data.frame(A=factor(letters[1:25]),B=runif(25), C=sample(LETTERS[1:4],25,replace=TRUE)) and I want to create a dotplot: library(lattice)dotplot(A ~ B | C, data=dfr, scales=list(y=list(relation="free"))) but this puts uneven spaces along the y-axis in each panel. drop.unused.levels=TRUE will drop conditioning variables, but does not affect the levels in the y-variable. I can get something like what I want with ggplot2:library(ggplot2)ggplot(data=dfr,mapping=aes(x=B,y=A)) + geom_point() + facet_wrap( ~ C,scales="free_y") I wonder if this is possible in lattice?
