Dang!!! Forget it. My random restricted permutation generator doesn't ``quite'' work. Further testing --- which I should've done before posting (sigh) --- reveals that it can get into a situation in which there's nothing left to sample from, and it still needs to fill out the permutation. I.e. it has painted itself into a corner.
Perhaps one could put in a test for this situation and just start again if it happens, but this makes me uneasy. What happens to the ``equal probability'' of all the generated permutations? Mebbe somebody else can come up with something cleverer. Sorry if I got your hopes up. cheers, Rolf Turner [EMAIL PROTECTED] ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
