The output layouts can be specified using the <em>layout</em> option.

<p>

Three layouts can be specified:
|
|
|
<ul>
|
|
|
<li><em>row</em> - Row order, one vector sample point value per row</li>
|
|
|
- <li><em>col</em> - Column order, create a column for each vector sample point of a single time step/raster layer</li>
|
|
|
- <li><em>timerow</em> - Time order, create a column for each time step, this order is the original r.what output, except that the column names are the time stamps</li>

In the following examples we sample a space time raster dataset that contains
