R return corrplot as object
corrplot plots a correlation matrix, but it does not return a graphical object (grob) I would like to plot several correlation matrices on a single page. For normal plots, I would use grid.arrange from the gridExtra package. However since corrplot only prints and does not return an object, I can't see how to do this. Is there a workaround or a better alternative to corrplot ? There's the old standby par(mfrow=c(x, y)) where x is the number of rows you wish to plot and y the numberof columns. It then posts across and then down as you call the plots. par(mfrow = c(2, 2)) corrplot(cor(mat1))
