[R] Sample size

Dear R-list, I have to design the validation of a score (ordinal values between 0 and 6) reputed to separate 4 groups of patients with known frequencies in the population. I think the more accurate is to calculate sample size under median test. Is there a function for that in R (not in the pwr
