The R rating (in the US) does reduce box office though, like with Blade Runner 2049 this year. Generally the budgets given to them are lower, because the audience that can see them is more limited. A lot of adults don't have time to go to the cinema, unless it is to take their children to a family-friendly film, hence children's animations being such a big deal now for film-companies.

Sometimes you get a breakout horror film that does well, and also R-rated comedies can do well.
