Hi all,
I want to get the index numbers of all elements of a vector which match any
of a long series of possible values. Say x - c(1,2,3,4) and I want to know
which values are equal to 1, 2 or 4. I could do
which(x == 1 | x==2 | x==4)
[1] 1 2 4
This gets really ugly though, when the list of
2 matches
