Title: | R Interface to the 'DieHarder' RNG Test Suite |
---|---|
Description: | The 'RDieHarder' package provides an R interface to the 'DieHarder' suite of random number generators and tests that was developed by Robert G. Brown and David Bauer, extending earlier work by George Marsaglia and others. The 'DieHarder' library code is included. |

The random
package provides an interface to the dieharder suite
of random number generators.
## Default S3 method: dieharder(rng="mt19937", test="diehard_runs", psamples=100, seed=0, verbose=FALSE, inputfile="", ntuple=5) ## S3 method for class 'dieharder' print(x, ...) ## S3 method for class 'dieharder' summary(object, ...) ## S3 method for class 'dieharder' plot(x, ...) dieharderGenerators() dieharderTests()

rng |
Either a single character vector, or an integer index, selecting a random-number generator to be tested. |
test |
Either a single character vector, or an integer index, selecting a dieharder test to be used. |
psamples |
An integer for the number of probability values samples underlying the main Kolomogorov-Smirnov test. |
seed |
An integer seed that is to be used for the dieharder rng; if 0, a new random seed is generated. |
verbose |
A switch selecting verbose or silent operation. |
inputfile |
File to read rng draws from for the |
ntuple |
A integer selecting the ntuple length for tests on short bit strings that permit varying length such as RGB bitdist. |
x |
A dieharder object. |
object |
A dieharder object. |
... |
Other arguments passed on. |
The current list of generators can be generated dynamically
using the dieharderGenerators()
function. Entries with
id
below 200 are from the GNU Scientific Library, entries with
id
greater or equal to 200 and less than 400 are from Dieharder itself,
entries with id
greater or equal to 400 and less than 500 are from GNU R,
entries with id
greater or equal to 500 and less than 600 are
hardware-based (which is system-dependent), and entries with
id
greater or equal to 600 are user-contributed.
The current list of tests can be generated dynamicall using the
dieharderTests()
function.
An object of class dieharder
, which inherits from the class
htest
commonly used for test statistics is returned. It
contains the members
