In R0.64.0, try as.numeric(is.na(c(NA,NA,1))) as.numeric(c(T,T,F))
My version says

[1] 1 1 0

[1] 1 1 0 which I think is ok?
Mine has
as.numeric(is.na(c(NA,NA,1)))
[1] -1 -1 0 Which is obviously not OK... Seems to affect all numeric NA's:
as.numeric(is.na(as.numeric(NA)))
[1] -1 This is on RedHat 5.2 (As Jim, I suspect) Ick!
