R help - Sep 2006 - extract a value from vector

A quick question, please!

How do you extract a certain value of vector?
i.e. x = c(2,5,3,6,21,3,6,24, ....)

How do you get the 1st one (which is 2); the 5th one (which is 21); etc?

thx much,

 ej

Simple, Ethan:

x[1], x[5], ...

Paul

I'm not quite sure what you mean.  To get the first item in a vector you use
> x[1]
[1] 2
> x[5]
[1] 21

Is that what you want?
