Hi all, 

I am trying to create a vector with the information contained in a determined matrix. Let me explain myself. I have a vector like this:

        q <- c("a","a","c","b","d","d","a","e","b","a")

And a matrix like:

        s1 <- c("a","b","c","d","e","f","g","h","i","j")
        e <- c("A","B","C","D","E","F","G","H","I","J")
        s <- cbind( e, s1 )


The matrix s contains the correspondences between vector q and e. And I want a vector of elements of vector e, but in the order of q. The result should be like:

        q <-  c ("a","a","c","b","d","d","a","e","b","a")

        res<-c ("A","A","C","B","D","E","A","E","B","A")

So I have to take the elements of vector e and make a matching with elements in vector q. Any idea?Sorry If I didn't explain myself well.

Thanks

Patricia
