This may be a doc error or a coding bug.
The help page for sample says:
"Non-integer positive numerical values of n or x will be truncated to
the next smallest integer, which has to be no larger than
.Machine$integer.max."
This is not true:
> table(sample(2.5, 1000000, replace = TRUE))
1 2 3
399933 399716 200351
We shouldn't have those 3's if truncation of x had occurred.
