I quite like this solution:

[1] 3 3 2 5 2 3 5 3 1 6

Maybe, but match(Y,X) would be more to the point.

i hope it helps you.

does this do what you want?
sapply(y,function(y){which(y==x)})

Hallo,
I have two vectors of different lengths which contain the same set of
values:
X < -c(2,6,1,7,4,3,5)
Y <- c(1,1,6,4,6,1,4,1,2,3,6,6,1,2,4,4,5,4,1,7,6,6,4,4,7,1,2)
How can I replace the values in Y with the index (!) of the corresponding
values in X. So 2 appears in X in the first coordina
8 matches
