(say scale , shape 1.) getting 100 random variables easy... rgamma(100, shape = 1, rate = 1) but how can accomplish these values range 0 100? edit make question clearer. 100 values drawn should scaled beween 0 , 10. highest drawn value 10 , lowest 0. sorry if not clear... edit no2 add context random numbers need: want draw "system repair times" follow distributions. however, within system simulation there binomial probability of repairs beeing "simple" (i.e. short repair time) , "complicated" (i.e. long repair time). need function provides "short repair times" , 1 provides "long repair times". threshold differentiation between short , long repair times. again, hope makes question little clear...
