Methods for Function simplifyr in Package `distr'
If you want to generate many random numbers, you should use simplifyr with a big size to be sure, that your numbers are really random.
signature(.Object = "UnivariateDistribution"): After several transformations of a given distribution it may take quite a long time to generate random numbers from the resulting distribution. simplifyr generates a certain number, by default $10^5$, of random numbers once. This pool of random numbers forms the basis for further uses of the r-method. That is, random numbers are generated by sampling with replacement out of this pool.
F <- ( Norm() + Binom() + Pois() + Exp() ) * 2 - 10 system.time(r(F)(10^6)) simplifyr(F, size = 10^6) system.time(r(F)(10^6))
