Can you add some logic that says as soon as the first character of an
argument is not -, then the rest should be interpreted as R code?
Obviously that won't work for something like %R -1, or even %R -X,
where X is an R variable and a real option, but it should handle cases
like this where the - clearly doesn't denote an option.
