SamplingPatternPriorPoints-class

A class for storing a sampling pattern consisting of existing points and new points. The new points are the centers of gravity of their stratum.

classes

Spatial coverage sampling and random sampling from compact
geographical strata created by k-means. See Walvoort et al. (2010)
<doi:10.1016/j.cageo.2010.04.005> for details.

SamplingPatternPriorPoints-class function

Objects can be created by calls of the form <code>new("SamplingPatternPriorPoints", ...)</code>. However, objects are usually created by calling <code>spsample</code>.

Objects from the Class

<dl>
 <dt><code>isPriorPoint</code>:</dt>
<dd>Object of class <code>"logical"</code>, which is <code>TRUE</code> is the location is a prior point, and <code>FALSE</code> if it is not.</dd> <dt><code>sample</code>:</dt>
<dd>Object of class <code>"SpatialPoints"</code>, containing the sampling locations</dd>
