Title
Body
I am wondering if there is a built-in function in R which applies a function to each element of the matrix (of course, the function should be computed based on matrix indices). The equivalent would be something like this: matrix_apply <- function(m, f) { m2 <- m for (r in seq(nrow(m2))) for (c in seq(ncol(m2))) m2[[r, c]] <- f(r, c) return(m2) } If there is no such built-in function, what is the best way to initialize a matrix to contain values obtained by computing an arbitrary function which has matrix indices as parameters?
