qqnorm and qqline in ggplot2

Question

Say have a linear model LM that I want a qq plot of the residuals. Normally I would use the R base graphics:

qqnorm(residuals(LM), ylab=\"Residuals\")
qqline         


        

Answer 1

ggplot2 v.3.0.0 now has an qqline stat. From the help page:

df <- data.frame(y = rt(200, df = 5))
p <- ggplot(df, aes(sample = y))
p + stat_qq() + stat_qq_line()
