The GGally::ggpairs(). provides the location of a plot according to the display order. The first, without color, strictly provides detail about the distribution and correlation between each pair created from our six predictor variables. Pearson correlation is displayed on the right. In summary, the pairs () and ggpairs () functions create a scatter plot matrix that can compare the correlations among data.
