factor labels in model.frame

Hello,

model.frame changes the factor labels when na.action =
na.omit.

f <- gl(3, 2, 6, paste('m', 1:3, sep = ''))
r <- c(NA, NA, 3:6)
mf <- model.frame(~ r + f, na.action = na.omit)
mf

  r  f
3 3 m1
4 4 m1
5 5 m2
6 6 m2

But it seems like it should be this

mf

  r  f
3 3 m2
4 4 m2
5 5 m3
6 6 m3

intead.

It certainly should, and on my machine it is (both Linux and Win2k). I
don't see how you can get the first answer.

Hmm, I rebooted my computer and now it works fine. 
How weird is that?

Thanks a lot Thomas,
