Hi, when I execute
order(letters, LETTERS, 1:26) then everything is fine. But if I execute order(letters, LETTERS, 1:26, na.last=c(T,T,T), decreasing=c(F,F,F)) I get the error message Error in method != "radix" && !is.na(na.last) : 'length = 3' in constraint to 'logical(1)' Shouldn't both give the same result?
