Missing values in time series
...or this - I'm sure I'm missing something somewhere... I've got a time series with several of missing values in it that I want to torture with R. But ts doesn't like the NA's, and I can't find any documentation telling me what to do about it. Help!

Extracting vectors from matrices
...e observed responses, and I want to extract the probabilities for the observed responses. As a toy example, if I have x <- matrix(c(1,2,3,4,5,6),2,3) y <- c(1,3) and I want to extract the numbers in x[1,1] and x[2,3] (the columns being indexed from y), what do I do?

Normally I would switch to drawing the graph in Postscript, but my collaborator's computer won't handle it.

"New" problem with polr (or optim, or ...)
Hello from a presently sunny Helsinki! I've bee trying to repeat an analysis I did about 18 months ago (the reviewers of the paper want something adding to it). I'm using R1.5.0, but I couldn't see anything in the list of changes between this and 1.5.1 to suggest it would act any differently.
