If the result is limited to just the counts of 1,2 and 3, you can do the following: > habs <- matrix(sample(1:3, 50, TRUE, prob=c(.6,.2,.2)),5,10) > habs [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,]132113111 2 [2,]12313

here's the code to generate the matrix set.seed(1) types = c(1,2,3) n=5 p=1 pop.props = c(0.6,0.2,0.2) x=matrix(pop.props,nrow=n,ncol=length(pop.props), byrow=T) b=10 habs = rMultinom((x),b) print(habs) -- View this message in context: http://r.789695.n4.nabbl
