Clearly the poor user needs to export something to one of those archaic stats
systems like SAS or SPSS :)

Hi,

I don't think this would work -- the is.na function is the way to go:
R> a <- c(1,2,3,NA,NA,10,20,NA,NA)
R> a
[1] 1 2 3 NA NA 10 20 NA NA
R> a[a == NA] <-999
R> a
[1] 1 2 3 NA

Well, with is.na() there is a much better chance to make it work
