How many vectors to generate
These are wrappers for the quasi-random sequence
functions from the GSL http://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
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_memcpy (because these don't make sense within R.)
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
Each row is a vector in the quasi-random sequence.
