Find Site Indexes With a Yield Table

Provides generic data structures and algorithms for use with forest
mensuration data in a consistent framework. The functions and objects
included are a collection of broadly applicable tools. More specialized
applications should be implemented in separate packages that build on this
foundation. Documentation about 'ForestElementsR' is provided by three
vignettes included in this package. For an introduction to the field of
forest mensuration, refer to the textbooks by Kershaw et al. (2017)
<doi:10.1002/9781118902028>, and van Laar and Akca (2007)
<doi:10.1007/978-1-4020-5991-9>.

site_index function

<dl><dt>age</dt>
<dd>Age (years) of the stand to be site indexed</dd>
<dt>size</dt>
<dd>Size value, typically a height (m), of the stand to be site
indexed. Must correspond to the parameter <code>si_variable</code> (see below)</dd>
<dt>ytable</dt>
<dd>A yield table, must be an <code>fe_yield_table</code> object</dd>
<dt>si_variable</dt>
<dd>Name of the stand size variable, typically a height (m),
to be used for site indexing. Must correspond to the parameter <code>size</code>
(see above). If <code>si_variable</code> is not part of the yield table object's
slot <code>$site_index_variable</code>, the function will terminate with an
error.</dd></dl>
