filling a matrix who's entries are a function of the indices?
Dear R list,
What's the best way in R to fill a matrix who's entries depend on some
function of the indices? I'm currently doing:
Q <- matrix(0, k, k)
for (A in 1:k) {
for (B in 1:k) {
Q[A,B] <- my.function(A,B)
}
}
but I wonder if there is a more terse way.
