These are wrappers for the quasi-random sequence
functions from the GSLhttp://www.gnu.org/software/gsl with
arguments corresponding to those from the library, with a few exceptions.
In particular: I have used dim where the GSL uses just d;
I have added the n argument to the qrng_get function, so that
a single call can generate n vectors; I have not provided R
functions corresponding to qrng_free (because R will automatically
free the generator when it is garbage collected) or qrng_state or
qrng_memcpy (because these don't make sense within R.)
Value
qrng_alloc, qrng_clone and qrng_init return an external pointer
to the C structure representing the generator. The internals of this structure
are not accessible from within R.
qrng_name returns a character vector giving the name of the generator.
qrng_size returns an integer value giving the internal memory
usage of the generator.
qrng_get returns a matrix with n rows and dim columns.
Each row is a vector in the quasi-random sequence.
