Input

Argument Type Description

Argument	Type	Description
`G`	any	A space- or comma-separated list of column names Rows are in the same group if their values for all of the columns listed in `G` are the same. If `G` is omitted, all rows are considered to be in the same group. If any of the columns listed in `G` contain N/A, the N/A value is considered a valid grouping value.
`S`	integer	The name of a column in which every row evaluates to a 1 or 0, which determines whether or not that row is selected to be included in the calculation If `S` is omitted, all rows will be considered by the function (subject to any prior row selections). If any of the values in `S` are neither 1 nor 0, an error is returned.
`O`	integer	A space- or comma-separated list of column names that determine the row order within a particular group If `O` is omitted, the order is the current display order of the table. If any of the values in `O` are N/A, an error is returned.

G

any

A space- or comma-separated list of column names

Rows are in the same group if their values for all of the columns listed in G are the same.

If G is omitted, all rows are considered to be in the same group.

If any of the columns listed in G contain N/A, the N/A value is considered a valid grouping value.

S

integer

The name of a column in which every row evaluates to a 1 or 0, which determines whether or not that row is selected to be included in the calculation

If S is omitted, all rows will be considered by the function (subject to any prior row selections).

If any of the values in S are neither 1 nor 0, an error is returned.

O

integer

A space- or comma-separated list of column names that determine the row order within a particular group

If O is omitted, the order is the current display order of the table.

If any of the values in O are N/A, an error is returned.

Return Value

For every row in each group defined by G and ordered by O (and for those rows where S=1, if specified), g_last1 returns an integer value of 1 if this is the last row in that group. Returns a 0 otherwise.

Sample Usage

<base table="pub.doc.samples.ref.func.g_func_time_series_sample_usage"/>
<willbe name="g_last1_1" value="g_last1(state;include;order)"/>
<willbe name="g_last1_2" value="g_last1(state city;include;order)"/>

Additional Information

The t_ version of this function defaults the G argument and omits the S argument. The default for G is set at table load time based on the organization of the table.
