[R] Alternative to list()

[Jonathan Baron]

>Suppose I have a dataset with 10 columns, let's call it "foo".

>(Is there any other alternative, just out of curiosity?)

>But, if I only want, say, column 1, 4 and 7, I tried:
>     fooNew <- list( x =3D foo[ ,1], y =3D foo[ ,4], z =3D foo[ , 7]  )
>then when I type=20
>     fooNew
>I got a list of:
>  $x
>   ....
>   ....
>  $y
>   ....
>   ....
>  $z
>   ....
>   ....

>However what I really want is for them to be in vector/column form.  How =
>would I do this?

foo[,c(1,4,7)]
