Re: [R] Question about setdiff()

There are two kinds of set difference: the usual set difference , also called the asymmetric difference or relative complement, and the symmetric difference . In R, setdiff(a,b) is

Thanks everyone! It is just as I expected, I just didn't understand how setdiff() works. Raphael On 6/2/14, Pascal Oettli wrote: > Hello, > > From the help page: "Performs *set* union, intersection, (asymmetric!) > difference, equality and membership on two vectors." > > Hope this helps, > Pasca

[R] Question about setdiff()

Hello everyone, I have a question which is probably rooted in my lack of understanding when it comes to math. I just did the following: v <- c(1:20) w <- c(11:30) setdiff(v, w) and got: 1 2 3 4 5 6 7 8 9 10 Then I did the following: setdiff(w, v) and got, not surprisingly: 21 22 23 24 25 26 27
