The following function delivers all permutations of 1:n. all.perm <- function(n) { p <- matrix(1, ncol = 1) for (i in 2:n) { p <- pp <- cbind(p, i) v <- c(1:i, 1:(i - 1)) for (j in 2:i) { v <- v[-1]

I think I've discovered what went wrong. My workspace included a function wilcox.test formerly copied from ctest. Now ctest ist part of the distribution and because of that I always got the message: [Previously saved workspace restored] Error in autoload("wilcox.test", "ctest") : Object already exists I didn't take care of this message. Now I removed

Hello all, I wonder if there is a package including a program to display a 3dim histogram.

I have two lists of equal lengths. Each one consists of vectors. Is there an elegant way to combine them elementwise? Elegant means: without loops. For instance, for > jja_list(1:3,4:7) > jjb_list(rep(0,4),(2,5)) I would like to get: > list(c(1:3,rep(0,4)),c(4:7,rep(2,5))). --- D.Trenkler --- ************************************************************************ *********

I'm an old APL fossil and I got used to work with nested arrays there. In APL(2) you can write 1+(1 2 3)(4 5 6 7 8 9) and get (2 3 4)(5 6 7 8 9 10). A similar concept is R's lists. So it takes me by surprise to learn that 1+list(1:3,4:9) delivers an Error in 1 + list(1:3, 4:9) : non-numeric argument to binary operator Is there any particular reason why this doesn't work

For some small sample sizes I would like to exemplify the combinatorics underlying certain nonparametric tests like Mann-Whitney-Wilcoxon, Kruskal-Wallis and Spearman's rank correlation. I have written a function all.perm which delivers all permutations of 1,2,...,n and which works reasonably well. This can be used to generate P(R=r) of Spearman's rank correlation:

Excuse me if this question has been answered before. I just came across "Writing R documentation" in the "Writing R extensions" manual. Under section 2.9: "Processing Rd format" I only find hints at generating the Rd format on a Unix platform. Have I overlooked how to generate them under Windows? Any help is gratefully appreciated. --- D.Trenkler ---

Dear R-community, not to re-invent the wheel I wonder if someone of you has ever written a function to compute the GHK smooth recursive simulator to estimate multivariate normal probabilities. See for instance page 194 of @BOOK{Greene97, author = {William H. Greene}, year = 1997, title = {Econometric Analysis}, edition = {3rd}, publisher = {Prentice-Hall}, address = {New Jersey

It took me by surprise to find that choose(4,5) delivers [1] NaN Warning message: NaNs produced in: choose(n, k) If we look at choose(4,5) as the number of ways of choosing 5 objects from 4 I would have expected 0 as result. Furthermore dhyper(5,4,6,5) does deliver 0 and this essentially equivalent to choose(4,5)*choose(6,0)/choose(10,5).

To whom it may be concernedDear all: i am a statistics of Humboldt university in berlin. I need R-2.4 for my data analysis, but unfortunately, it does not work. The installation works smoothly, but when I double click on the shortcut or from the start menu, the error warning jumps out. My computer is in german system and so do the error information. The following is the error warning and its
