[R] na.omit

[buerkle@hawaii.edu]

Why is it that when a vector contains no NAs, na.omit returns an empty
vector rather than the object/vector that was passed to it?  

>na.omit(c(1,2,3,4))          
numeric(0)

in contrast ...

>na.omit(c(1,2,3,NA))
[1] 1 2 3
attr(,"na.action")
[1] 4
attr(,"na.action")attr(,"class")
[1] "omit"

Thanks, Alex
