Thanks Paul.
I am not sure if I understood well, but when I do it then I have only two
columns left:
> L3 <- LETTERS[1:3]
> (d <- data.frame(cbind(x=1, y=1:10, z=11:20), fac=sample(L3, 10,
> replace=TRUE)))
x y z fac
1 1 1 11 C
2 1 2 12 B
3 1 3 13 B
4 1 4 14 C
5 1 5 15 C
6 1 6 16 B
7 1 7 17 C
8 1 8 18 C
9 1 9 19 B
10 1 10 20 C
> d <- d[,c(2,1)]
> d
y x
1 1 1
2 2 1
3 3 1
4 4 1
5 5 1
6 6 1
7 7 1
8 8 1
9 9 1
10 10 1
But I have more than two columns in my data.frame.
