R help - Dec 2018 - Random seed

I have known from the old days to set a random seed of a LARGE ODD 
NUMBER. Now I read instructions of set.seed and it requires ANY INTEGER. 
Any idea? Or, does it matter. Thanks.

It doesn't matter. The whole point is to make the pseudo-random sequence
repeatable... unless you have a specific reason to avoid repeatability.

For the record, low bitcount RNGs are relatively sensitive to initialization [1]
such that rules like the one you reference might make sense for specific
designs, but the default RNG used in R is much much more sophisticated than that
[2].
