Set the background color as the intensity of data in corrplot

Question

I have a matrix of data and I want to use the background color to show the value of the element of the matrix so the darker the background the bigger the matrix element. I have used corrplot like this:

corrplot(overlaps[[1]], method="number", is.corr=FALSE, type="full",
         cl.lim=c(0,100), addgrid.col="red", addshade="positive")

and the matrix would be like below:

But I want the background to show the intensity not the numbers as here. What should I do?

Thank you in advance

Answer 1

library(corrplot)
m <- matrix(rnorm(1000), ncol = 10)
corrplot(cor(m), method = "color", type="full", addgrid.col = "red",
        addshade = "positive", addCoef.col = "black")

Although I'm not sure if this is the best way to display correlations...
