draw_int(X;Y)
Returns a random integer using a given seed that remains persistent (sticky) even after selections or links with expansion are used.
Syntax
draw_int(X;Y)Input
| Argument | Type | Description |
|---|---|---|
X |
integer | A scalar value
|
Y |
integer | A scalar value other than 0. |
Return Value
A random integer is drawn, with replacement, for each row.
If the current table has only one segment or is a tabulation, then Y may
also be negative; in this case |Y| must be greater than or equal to the
number of selected rows, and random integers between 0 and |Y|-1 are drawn
without replacement.
If X or Y is N/A or if Y is 0, an error
is returned.
Note:
draw_int(X;Y) will work correctly even when selections or links with
expansion (expand="1") are used because the results are sticky. This means that the random integer generated by the
function for each row will be the same after the expansion. When the
drawint(X;Y) function is used, a different integer will be generated
for each of the expanded rows.
