Abby, that is a fantastic suggestion! It seems obvious now that you've said it. Why didn't I think of that? Thank you, Tommy On Fri, Jul 31, 2020 at 12:01 AM Abby Spurdle wrote: > > 3. In C++: Draw millions of times from a Categorical(p) distribution, > where > > "p" is recalculated after each

reinventing the wheel, but instead relying on the accumulated experience of the folks that are writing these RNGs. Knowing more about the bigger use, does this still strike you as obviously problematic? Best, Tommy On Thu, Jul 30, 2020 at 4:49 PM Duncan Murdoch wrote: > On 30/07/2020 4:

[Rd] Seeding non-R RNG with numbers from R's RNG stream

2020-07-30 Thread Tommy Jones
Hi, I am constructing a function that does sampling in C++ using a non-R RNG stream for thread safety reasons. This C++ function is wrapped by an R function, which is user facing. The R wrapper does some sampling itself to initialize some variables before passing them off to C++. So that my users
