Hi,
Imagine a vector x with elements (1,2,1,1,3,5,3,3,1) and a vector y with
elements (2,3). I need to find out what elements of x match any of the
elements of y.
Is there a simple command that will return a vector with elements
(F,T,F,F,T,F,T,T,F). Ideally, I would like a solution that works with
dataframe colums as well.
I have tried x==y and it doesn't work.
x==any(y) doesn't work either. I realize I could write a foor loop and go
through each element of y asking if it matches any element of x, but isn't
there a shorter way?
Thanks,
Gonçalo
