Dear all, Is there a simple way to add a qqline to the Q-Q plot plot.lm() produces for which = 2? If not, I might write one, but how should this preferably be implemented? Make qqline() generic and add a qqline.lm() method? Add an argument to plot.lm()? Have plot.lm() output something invisibly that qqline() can chew directly? Have plot.lm() output something invisibly that abline() can chew? Something else?
