Creating same random number sequence in Python, NumPy and R

by

use rpy2 to call r in python, here is a demo, the numpy array data is sharing memory with x in R:

import rpy2.robjects as robjects

data = robjects.r("""
set.seed(1)
x <- runif(5)
""")

print np.array(data)

data[1] = 1.0

print robjects.r["x"]
