See the NEWS, the RNG has been changed, use RNGversion

Dear all,
I did all this work with older R (R-3.5.3.patched and older)
but now with R3.6 I cannot replicate the results.
Below I sample 60 observations from 1:500 using the sample command with
a random seed of 123. I get different results. Advice appreciated.

9.0 122.2 205.0 236.1 364.2 493.0
Under R-3.6.0 use, e.g.
RNGversion("3.5.2")
to get reproducible results from the older RNG.
Best,
