buffer_indices

Apply an inclusion radius and exclusion buffer to indices

Functions and classes for spatial resampling to use with the
'rsample' package, such as spatial cross-validation (Brenning, 2012)
<doi:10.1109/IGARSS.2012.6352393>. The scope of 'rsample' and
'spatialsample' is to provide the basic building blocks for creating
and analyzing resamples of a spatial data set, but neither package
includes functions for modeling or computing statistics. The resampled
spatial data sets created by 'spatialsample' do not contain much
overhead in memory.

buffer_indices function

<dl><dt>data</dt>
<dd>An object of class <code>sf</code> or <code>sfc</code>.</dd>
<dt>indices</dt>
<dd>List of indices in each fold generated by <code>split_unnamed()</code>.</dd>
<dt>radius</dt>
<dd>Numeric: points within this distance of the initially-selected
test points will be assigned to the assessment set. If <code>NULL</code>, no radius is
applied.</dd>
<dt>buffer</dt>
<dd>Numeric: points within this distance of any point in the
test set (after <code>radius</code> is applied) will be assigned to neither the analysis
or assessment set. If <code>NULL</code>, no buffer is applied.</dd></dl>
