[Rd] A different error in sample()

[Duncan Murdoch]

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.
