Hi, dear R-helpers,

I have a simple question regarding selecting subset of a variable based on
another variable.
Here is the example:

xx=rnorm(10)
id=sample(1:10, 10)

temp=c(6, 1, 8, 2)

Now, all I want is xx's that their id are 6, 1, 8, 2, instead of the
position.

Any suggestions ?

Thank you all your help !!

Carrie
