corrplot in r

The R package corrplot provides a visual exploratory tool on correlation matrix that supports automatic variable reordering to help detect hidden patterns among variables. 1 It is very easy to use and provides a rich array of plotting options in visualization method, graphic layout, color, legend, text labels, etc.. 1 Additionally, a correlogram can be plotted in R to highlight the most correlated variables in a data table. 2 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. 2 The color of the correlogram can be customized, and the correlation coefficient can be computed using a custom R function. 2
