In GGally::ggpairs correlation values are shown with *'s as seen in the figure below. I'd like to change the *s to show the numerical significance values.
GGally::ggpairs(data = iris[, 1:4],
upper=list(continuous=wrap(ggally_cor,displayGrid=FALSE, stars=TRUE)))
I tried to extract the significance values in a function before the graph, but I can't integrate them to ggpairs afterward.
