"SIGNIFICANT USER-VISIBLE CHANGES
The default method for generating from a discrete uniform distribution
(used in sample(), for instance) has been changed. This addresses the
fact, pointed out by Ottoboni and Stark, that the previous method made
sample() noticeably non-uniform on large populations. See PR#17494 for
a discussion. The previous method can be requested using RNGkind() or
RNGversion() if necessary for reproduction of old results. Thanks to
Duncan Murdoch for contributing the patch and Gabe Becker for further
assistance."
If so, testing with
export _R_RNG_VERSION_=3.5.0
might remove/explain those errors.
Just a thought
