Correlation plot
R offers other ways of displaying the correlation matrix. With the corrplot
package, the visualization of correlations is made easier and more powerful by allowing you to represent the correlations with numbers, symbols, colors, and more.
In this exercise, you will use the provided correlation matrix cor_mat
and the corrplot()
function to draw some correlation charts.
This exercise is part of the course

Exercise instructions
- Plot the correlation matrix of
cor_mat
using default settings - Change the
method
to display numbers instead of circles - Change the
method
to display colors instead circles - Display only the upper triangle of the correlation matrix using numbers
