Besides wording of the documentation re truncating vs rounding, there
is something peculiar going on with the fractional part of n:
> table(sample.int(2.5, 1e6, replace = TRUE))
1 2 3
399051 401035 199914
> table(sample.int(3, 1e6, replace = TRUE))
1 2 3
332956 332561 334483
> table(sample.int(2.01, 1e6, replace = TRUE))
1 2 3
497173 497866 4961

Good day,
The use of "rounding" also doesn't make sense. If The number is halfway between
two integers, it is rounded to the nearest even integer.
round(2.5)
