Hello,
I want to create a flexible code for the following example: In stead of using a different code for each n (as in my example below), I want to write a general code for every n (n from 1 to 10). I tried a lot of things, but I always got stuck with the number of subloops or witch closing the brackets. Any suggestions? Cheers, Peter Department of Mathematics and Statistics University of Canterbury New Zealand n <-2 matrixallo <- matrix(nrow=0,ncol=n) for(i in 1:20) { for (j in 1:20) { if (i+j == 20) { newentry<- cbind(i,j) matrixallo <- rbind(matrixallo,newentry) } } } n <-3 matrixallo <- matrix(nrow=0,ncol=n) for(i in 1:20) { for (j in 1:20) { for (k in 1:20) { if (i+k+j == 20) { newentry<- cbind(i,j,k) matrixallo <- rbind(matrixallo,newentry) } } } } This email may be confidential and subject to legal privilege, it may not reflect the views of the University of Canterbury, and it is not guaranteed to be virus free.
