Re: [R] Generating a new matrix using rbinom and a matrix of probabilities.

I think the following does what you want: probMatrix <- matrix(runif(5 * 5), 5, 5) binomialMatrix <- matrix(rbinom(5 * 5, 1, probMatrix), 5, 5) Patrick Burns [EMAIL PROTECTED] +44 (0)20 8525 0696 http://www.burns-stat.com (home of S Poetry and "A Guide for the Unwilling S User") Economics Guy w

[R] Generating a new matrix using rbinom and a matrix of probabilities.

I am having a little trouble getting R to do something without writing a couple of very awkward loops. I have a matrix of probabilities and I want to generate a new matrix of ones and zeros where each element in the new matrix is the result of a draw from a binomial distribution where the probabil
