Hello everyone!
First of all, please note that I'm working under Windows 7.
I have written a Gibbs sampler in R and I'm now in the process of translating
it in C++ to increase the speed. I'm relatively new to C++ and this question
may be trivial, but my search so far have been unsuccessful. In my Gibbs
sampler I am using some basic R functions (like the rep function for example)
and I was wondering if it was possible to call the R rep function (or any other
existing R function) from within my C++ code. (There may be an equivalent of
the rep function already in C++ but my main interest here is to learn if there
is a way to call the R function within C/C++)
I'm aware that you can call R random number generators as well as probability
distribution functions with the GetRNGstate() but what about other functions?
The sample of the C code below reveals what I would like to do regarding the
rep function.
extern "C" {
void Gibbs_Sampler (double *vect.PI, int *iteration)
{
int i;
for (int i=0; i<*iteration; i++)
{
...
PI.rep = rep(vec.PI,times=n) // Can we call the R rep
function such that this line of code (or any equivalent code) is valid?
...
}
}
}
Thanks,
