Hi everybody, Currently one can alter R's random number generation via RNGkind() in three aspects: the RNG itself, the method for drawing from the normal distribution and the method for generating integers within a range. For the first and second aspect it is possible to supply user defined methods. This is not the case for the last aspect, which is handled in R_unif_index. I think it would be interesting to add a comparable hook there as well. What do you think? Ralf
