How do you test the normality of the residuals in ANOVA? Is there also a way of plotting the residuals?

Hi Emanuele,
You can use the normplot function to obtain the normality plot of the residuals. This documentation page contains several tests for normality of residuals in ANOVA.
The link to the answer here can also be helpful in obtaining the residuals necessary for plotting.
Hope this helps!
