dotplot(samp.time~conc|site, data=test, scales=list(x=list(log=10), y = list(relation = "free")), layout=c(1,5), strip=FALSE, strip.left=TRUE ) my objective is to use “site” as conditioning variable but with “samp.time” correctly grouped by “site”; the problem here is to ensure that levels of “samp.time” within each “site” are contiguous as otherwise they would be not contiguous in the dot plot itself (i.e, avoid that sort of holes in between y axis categories -see dotplot -) I’ve been trying with this but without much success test$samp.time.new<- with(test,reorder(samp.time,as.numeric(site))) dotplot(samp.time.new~conc|site, data=test, scales=list(x=list(log=10), y = list(relation = "free")), layout=c(1,5), strip=FALSE, strip.left=TRUE ) I think (I hope) a possible different solution is to create for "ylim" a proper character vector of different length to pass to each panel of the dotplot (I’m not posting this attempt because too much confused up to now) can anyone point me in the right direction? any help much appreciated thank you -- View this message in context: http://r.789695.n4.nabble.com/lattice-dotplot-reorder-contiguous-levels-tp4643741.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
