Predicting the volume of the tree using diameter breast height by using training and test data models.

Description

The data file and shape file is combined for generating models. First, converted into a spatial object with x and y, and crs- coordinate reference system, used for mapping and navigation Reads the total number of rows from whole data, and selects 70% at random to use as a training model, and the remaining number of rows is used as a testing model; then produces predicted model.
