[R] unexpected results with higher-order functions and lapply

I want to use lapply and a function returning a function in order to build a list of functions. > genr1 <- function(k) {function() {k}} > l1 <- lapply(1:2,genr1) > l1[[1]]() [1] 2 This was unexpected. I had expected the answer to be 1, since that is the value k should be bound to when genr1 is ap
