ggpmisc 0.3.4

This version (0.3.4) adds to stat_poly_eq() the ability to return F-value and P-value in addition to the equation of the polynomial, R2, AIC and BIC available in earlier versions of ‘ggpmisc’. The package code and examples have been updated to avoid the use of functions and methods that have been deprecated in recent updates to ‘ggplot2’.

library(ggpmisc) # version >= 0.3.4 !!
ggplot(mtcars, aes(x = wt, y = mpg, colour = factor(cyl))) +
  geom_smooth(method="lm") +
  geom_point() +
  stat_poly_eq(formula = y ~ x,
               aes(label = paste(stat(f.value.label), stat(p.value.label), 
                                 sep = "*`,`~")),
               parse = TRUE,
               label.x.npc = "right") +

The code above produces the plot below.
