My guess is that you're not getting what you expect from operator
precedence: note that
1:3 - 1
1:(3-1) #Not equal
If that doesn't fix it, you can use options(error = recover) to find
the values of your logical conditions at the exact moment an error is
thrown and see which one is NA but my money is on the above.
