na.omit

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)
Well, because there is a bug in na.omit.default. The problem is in the
section of code
omit <- seq(along = object)[is.na(object)]
nm <- names(object)
object <- object[-omit]
If there are no NA's in the object, then omit becomes a length 0
vector and -omit doesn't have the intended effect.
A temporary fix would be to insert
if (length(omit) == 0) return(object)
after the first line shown above.
We'll incorporate a fix for the next release. Thanks for reporting
the bug.
