R_chart.Correlation
The chart.Correlation() function from the PerformanceAnalytics package produces a very nice scatterplot matrix, with histograms, kernel density overlays, absolute correlations, and significance asterisks (0.05, 0.01, 0.001). mydata <- mtcars [ , c ( 1 , 3 , 4 , 5 , 6 ) ] # plot the data library ( PerformanceAnalytics ) chart.Correlation ( mydata )
