%description
A model that provides researchers with a powerful tool for the
classification and study of native corn by aiding in the identification of
racial complexes which are fundamental to Mexico's agriculture and
culture. This package has been developed based on data collected by
"Proyecto Global de Maíces Nativos México", which has conducted exhaustive
surveys across the country to document the qualitative and quantitative
characteristics of different types of native maize. The trained model uses
a robust and diverse dataset, enabling it to achieve an 80%% accuracy in
classifying maize racial complexes. The characteristics included in the
analysis comprise geographic location, grain and cob colors, as well as
various physical measurements, such as lengths and widths.
