Hi
Works for me, how did you tested it?
v - sample(letters[1:10], 17, replace=T)
d-data.frame(letters[1:10], 1:10)
d[match(v,d[,1]),2]
[1] 8 2 6 1 7 10 4 10 10 9 10 8 1 8 6 7 8

Try playing with match(). Something like

that is related to a matching value in a dataset (consisting of 17 rows).
Here's an example
The vector:
v - c(f,a,e,d,m,o,e,f,i,n,e,i,b,a,o)
The dataset's columns consist of the following values
