Dear alltogether, how can a delay like possible with par(ask=TRUE) be attained while using trellis-plots within a loop or something like that? the following draws each plot without waiting for a signal (mouse-klick), so par() does not work for that: library(nlme) for(i in 1:3) { fitlme <- lme(Orthodont) par(ask=TRUE) # does not work with trellis.... print(

Dear all, I am trying to write a function for visualizing ordinal model results. The function works fine with some values, but then I get "Error: subscript out of bounds" even there the index should be pointing a legal item. Code is below as well as the example of failure: plotProb <- function(pre.mat, parts, split, titles, xlab="") { par(mfrow = split) n <- 1

Of course I do have my own preferences (biased, of course) and opinions about the different packages, but I would also like to summarize in my paper the feedback I get from the R community.
