Dear useRs,

A few days ago, the initial version 0.1.0 of a new package 'random' was uploaded to CRAN.

The random packages provides convenient access to the non-deterministic random numbers provided by the random.org site created by Mads Haahr (http://www.random.org).

While certain hardware and software solutions that provide access to non-deterministic random-numbers exist, few if any are portable across all the hardware platforms R supports. Retrieving non-deterministic random numbers may be beneficial to seed parallel simulations with independent draws, to obtain portable initializations for other RNGs, to validate simulation with non-deterministic RNGs, or simply for fun and experimentations.

The package contains five simple functions

     randomNumber	(random integeres between min, max w/ duplicates)
     randomSequence	(random sequences between min, max w/o duplicates)
     randomBytes	(in hex, dec, oct or bin)
     randomBufferStatus (to query the server status)
     sufficientBits	(boolean test of randomBufferStats vs rec'ed value)

Also included are two vignettes that can be accessed via
     vignette("random-intro", package = "random")
     vignette("random-essay", package = "random")

'random-intro' provides some background on the package as well as initial test results using the dieharder suite by Robert G. Brown. I hope to expand on these tests in the near future. 'random-essay' is a transcript of the web essay at http://www.random.org/essay.html and provides some background on the random.org service.

Some information is / will be at

Comments or suggestions are more than welcome!

Regards, Dirk
