I have a problem sorting a table;

When I read a table into R by x <- read.table() I get something like this:

V1	V2	V3
yes	1	3
no	2	6
yes	3	9
no	4	12

Now I want to generate a vector of V2.
But R should only put in the numbers of V2 into the new vector when there is the entry "yes" in V1.

How can I realize that?

Thanks for help. I am getting crazy trying to solve that ...
