Dear Xavier, Perhaps you mean the qqPlot() function in the car package. If so, you should install the car package. As well, if anc0 is a linear or generalized linear model, qqPlot() has a method for plotting studentized residuals and you'd probably prefer to use that rather than extracting the residuals from the model.
I hope this helps, John ------------------------------------------------------- John Fox, Professor McMaster University Hamilton, Ontario, Canada http://socserv.mcmaster.ca/jfox/ > -----Original Message----- > From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of > CHIRIBOGA Xavier > Sent: February-13-15 4:33 PM > To: r-help@r-project.org > Subject: [R] qq-Plot function in version 3.1.2. > > Hello!
