Dear all,

I have a data frame called x2, which looks like:

> dim(x2)
[1] 2237     2
> x2[1:4,1:2]
    name                       id
1 STye                      hggd3
2 STy2                      bffbd2
3 qw22e                    bdbdbbbd7
4 deffrdff                    nnshfd3

and a vector called y, which looks like:

> dim(y)
[1] 135   1
> y[1:3,1]
[1] ABCDE BDH5  DESRP1

y is a subset of x2$name and I want to select the rows in x2 whose 'name'
match
y. Is there an easy way to do so?

I tried subset(x2, y) but it did not work.

Thanks much for your advice.

Alex
