Runuran (version 0.22.0)

unuran-class: Class "unuran" -- Universal Non-Uniform RANdom variate generators

Description

The class unuran provides an interface to the UNU.RAN library for universal non-uniform random number generators. It uses the Rbuilt-in uniform random number generator. [Advanced] -- UNU.RAN generator object.

code

unuran.new

Warning

unuran objects cannot be saved and restored in later Rsessions, nor is it possible to copy such objects to different nodes in a computer cluster.

However, unuran objects for some generation methods can be packed, see unuran.packed. Then these objects can be handled like any other Robject (and thus saved and restored).

All other objects must be newly created in a new Rsession! (Using a restored object does not work as the unuran is then broken.)
