Hi,
I was surprised that apply and sapply don't return the same results in
the example below. Can someone tell me what I'm missing?
> zls <- function(x) character(0)
> m <- matrix(0, nrow=2, ncol=2)
> apply(m, 1, zls)
character(0)
> sapply(m, zls)
[[1]]
character(0)
[[2]]
character(0)
[[3]]
character(0)
[[4]]
character(0)
