> The very existence of an "is.na<-" which accepts a logical > vector containing FALSE as well as TRUE ... And don't forget this is not the only usage of is.na<-. In fact it is designed to take any valid indexing value. For example: > a<-1:10 > is.na(a) <- 1:5 > a [1] NA NA NA NA NA 6 7 8 9 10 Wow. I really hate that. Someone tell me again why this is better than a[1:5] <- NA ??
