SyncRNG - Synchronized Random Numbers in R and Python
Description
The SyncRNG package provides a random number generator implemented in C and linked to both R and Python. This way, you can generate the same random number sequence in both languages by using the same seed.
The package implements a Tausworthe LSFR RNG (more details at https://gertjanvandenburg.com/blog/syncrng/). This is a very fast pseudo-random number generator.
Usage
There are two ways to use this package in R. It can be used as a reference class, where a SyncRNG object is used to keep the state of the generator and numbers are generated using the object methods. It can also be used as a user-defined random number generator using the strategy outlined in .Random.user. See the examples section below.

Examples
library(SyncRNG)
# As user defined RNG:
set.seed(0, 'user', 'user')
runif(2)
# [1] 3.666952e-04 6.257184e-05
set.seed(0, 'user', 'user')
rnorm(2)
# [1] 0.01006027 0.42889422
# As class:
s <- SyncRNG(seed=0)
s$rand()
# [1] 0.0003666952
s$rand()
# [1] 6.257184e-05
