Re: [Rd] Patch to add Beta binomial distribution. Mentor needed!

I'm trying to implement the Beta binomial distribution as a R package. I studied R-ext manual but still there are some problems. The code in C seems to work except for the rbetabinom function which is not very random (it always returns the same values for the same parameters). I have tried to use GetRNGstate(); and PutRNGstate(); but it give a SEG FAULT when I call GetRNGstate. You can try the code like this:

cd /path/to/src
cmake ./CMakeLists.txt

I can build and install the package but when I call the functions from R they always return NULL except for rbetabinom which remains hanged indefinitely.

Any advise?
