RDieHarder (version 0.0.7)

dieharder: Random numebr generator test suite

Description

The random package provides an interface to the dieharder suite of random number generators.

Usage

## S3 method for class 'default':
dieharder(rng="mt19937", test="runs", psamples=100, seed=0, rngdraws=100000, verbose=FALSE) 
   ## S3 method for class 'dieharder':
print(x, ...)
   ## S3 method for class 'dieharder':
summary(object, ...)
   ## S3 method for class 'dieharder':
plot(x, ...)
   dieharderGenerators()

Value

An object of class dieharder, which inherits from the class htest commonly used for test statistics is returned. It contains the membersp.valuefor the (Kuiper variant) of the Kolmogorov-Smirnov test of the null of a uniform distribution of test values generated by psamples tests of test using draws from rngdatathe vector of test statistics used for the Kolmogorov-Smirnov testmethodthe test method as returned by the dieharder librarydata.namea character vector describing the datageneratora text desciption of the generator as returned by the dieharder library
