t.vect.univar.html

<h2>DESCRIPTION</h2>

The module <em>t.vect.univar</em> computes univariate statistics of a
space time vector dataset based on a single attribute row.


<h2>EXAMPLE</h2>

The example is based on the <a herf="t.vect.observe.strds.html">t.vect.observe.strds</a>
example; so create the <b>precip_stations</b> space time vector dataset
and after run the following command:

<div class="code"><pre>
t.vect.univar input=precip_stations col=month
