quadrat2_tree.df

A dataset containing tree measurements from 25 quadrats (5 × 5 m each)
sampled in a forest fragment located at the campus of the University of Sao Paulo,
Ribeirao Preto, Brazil. This dataset corresponds to the same trees as in
<code>quadrat2_plot.df</code>, but includes simulated coordinates (in meters) for
each individual tree inside the quadrats. It is organized to demonstrate the
use of the function <code>BAplot()</code> with the argument <code>ind.coord = TRUE</code>.

datasets

Provides functions and example datasets for phytosociological
analysis, forest inventory, biomass and carbon estimation, and visualization
of vegetation data. Includes functions to compute structural parameters
[phytoparam(), summary.param(), stats()], estimate above-ground biomass
and carbon [AGB()], stratify wood volume by diameter at breast height (DBH)
classes [stratvol()], generate collector and rarefaction curves [collector.curve(),
rarefaction()], and visualize basal areas on quadrat maps [BAplot(), including
rectangular plots and individual coordinates]. Several example datasets are provided
to demonstrate the functionality of these tools. For more details see FAO
