bug with mapply() on an S4 object
Hi,
Starting with ordinary vectors, so we know what to expect:
> mapply(function(x, y) {x * y}, 101:106, rep(1:3, 2))
[1] 101 204 309 104 210 318
> mapply(function(x, y) {x * y}, 101:106, 1:3)
[1] 101 204 309 104 210 318
Now with an S4 object:
setClass("A", representation(aa="integer"))
a <- new("A", aa=101:106)
> length(a)
