Structurally guided sampling (SGS) approaches for airborne laser scanning (ALS; LIDAR). Primary functions provide means
to generate data-driven stratifications & methods for allocating samples. Intermediate functions for calculating and extracting important information
about input covariates and samples are also included. Processing outcomes are intended to help forest and environmental management
practitioners better optimize field sample placement as well as assess and augment existing sample networks in the context of data
distributions and conditions. ALS data is the primary intended use case, however any rasterized remote sensing data can be used,
enabling data-driven stratifications and sampling approaches.

vectorize function

<dl><dt>mraster</dt>
<dd>Spatraster. Raster to stratify. Layers in <code>mraster</code> must match the number of
<code>breaks</code> vectors provided.</dd>
<dt>breaks</dt>
<dd>Numeric. Vector of breakpoints for each layer of <code>mraster</code>. If <code>mraster</code> has multiple layers,
<code>breaks</code> must be a list with an equal number of objects.</dd>
<dt>nStrata</dt>
<dd>Numeric. A positive integer representing the number of desired classes
or a numeric vector of probabilities with values between <code>0-1</code>. If <code>mraster</code> has multiple layers,
<code>nStrata</code> must be a list with an equal number of objects.</dd></dl>
