The **biometrics** package aims to apply quantitative analyses to forest ecology, silviculture, and decision-support systems. Besides, the package helps to carry out data management, exploratory analysis, and model assessment.
The main goal of **biometrics** is to provide reliable mathematical procedures in a computing setting commonly used for quantitatively characterising trees and forests. As such, the package offers an array of functions that build summary description tables and graphs, such as stand tables and diameter distribution plots. Furthermore, the package has several data frames that help illustrate the application of the functions and teach topics related to forest ecology, silviculture, and forest biometrics. The package relies heavily on the work and teaching style of [Christian Salas-Eljatib](https://eljatib.com/).

Christian Salas-Eljatib is also indebted to several people who have contributed to individual data frames and functions: see credits in help pages.
Notice that most of the available dataframes have a counterpart with column names in Spanish. For instance, the dataframe 'mortaforest' has column names in English, but 'mortaforest2' has column names in Spanish. Both data frames have the same data.
