Machine Learning with R Cookbook - Second Edition

How it works...

In this recipe, we demonstrate how to use biplot to plot data and projections of original features for the first two components. In the first step, we demonstrate that we can actually use the first two components to create a scatter plot. Furthermore, if you want to add variables on the same plot, you can use biplot. In biplot, you can see the provinces with higher indicators in the agriculture variable, lower indicators in the education variable, and examination variables scores that are higher in PC1. On the other hand, the provinces with higher infant mortality indicators and lower agriculture indicators score higher in PC2.
