v_red_harvest_ubark_core

See documentation of <code>v_red_harvest_ubark</code> for most information,
this function is the workhorse behind, and should never be called directly by
a user.

internal

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>.

v_red_harvest_ubark_core function

<dl><dt>species_id</dt>
<dd>Vector of species ids (see
<code>v_red_harvest_ubark</code>), but for this core function to work,
<code>species_id</code> must be provided as <code>character</code>. This will and
should be not checked inside this function, because if used as intended,
that has happened before calling it.</dd>
<dt>v_orig_m3</dt>
<dd>Vector of wood volumes (m³) defined as standing over bark
(see documentation of <code>v_red_harvest_ubark</code>.)</dd>
<dt>params</dt>
<dd>A data frame comprising species (group) wise reduction factors.
The calling function has to take care that <code>v_red_harvest_ubark_core</code>
is called with a <code>params</code> that fits to the coding used in
<code>species_id</code>.</dd></dl>
