make_trees_dataframe

Build a 'trees' data.frame (tibble) as Required for fe_stand and
fe_stand_spatial Objects

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>.
