R^2 as option in stat_cor()

[philament]

I like the simplicity of quickly adding the correlation coefficient and p-value to a scatter plot produced with ggscatter(). It would be nice to be able to select the R^2 value instead of r as a method in stat_cor() .

I am totally agree !

Now, R2 is supported.

library("ggpubr")
# Default output
ggscatter(mtcars, x = "wt", y = "mpg", add = "reg.line") +
  stat_cor(label.x = 3)

# Use R2 instead of R
ggscatter(mtcars, x = "wt", y = "mpg", add = "reg.line") +
  stat_cor(
    aes(label = paste(..rr.label.., ..p.label.., sep = "~`,`~")), 
    label.x = 3
    )

Is it possible to achieve this but with the R² and p value on separate lines?
