Summary
This article explains how to plot a correlogram in R, a graph of correlation matrix that is used to highlight the most correlated variables in a data table. The R corrplot package is used to plot the graph of the correlation matrix, and there are seven different visualization methods that can be used to display positive and negative correlations in different colors. Additionally, the color of the correlogram can be customized, and the correlation coefficient can be computed using a custom R function.
