[R] Cutting vectors

[Patrik Waldmann]

I have one factor with say five levels (fact) of different size and a corresponding variable (var). I randomly generate five new levels (nfact ex. 2,2,1,5,4). What I would like to do is to extract the corresponding variable values into a new variable (nvar). I did try the following, why doesn't it work?  nvar<-var[fact==nfact[ ]]
