Alternative to list()
Hi,
Suppose I have a dataset with 10 columns, let's call it "foo".
Now if I want to extract out only column 2 ~ 8, then I know I can use either:
foo[ ,2:8]
or
fooNew <- list( foo[ ,2:8] )
(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 = foo[ ,1], y = foo[ ,4], z = foo[ , 7] )
