Length of the generated vectors. If len is a
single number all vectors will have this length. If
len is a numeric vector of length 2 it will produce
vectors with lengths between a minimum and maximum,
inclusive. For example len = c(1L, 10L) would produce
vectors with lengths between 1 and 10. To produce empty vectors
set len = 0L or a range like len = c(0L, 10L).
any_na
Whether NA values should be allowed.
big_int
Should integers near the maximum size be
included? This may cause problems because if the result
of a computation results in an integer larger than the
maximum it will be silently coerced it to a double.
left
The minimum possible value for generated
numbers, inclusive.
right
The maximum possible value for generated
numbers, inclusive.
