Hi all, I am trying to produce a half-normal plot of residuals from a GLM. I have found the qqnorm function for producing a normal plot but can't figure out how to produce a half-normal. Can anyone help with this? Thanks Malcolm ---------------------- MJ Price, Social Medicine epmjp at bristol.ac.uk
There is a halfnorm function in the faraway package.

Dear Malcolm, I don't think that anyone fielded this question earlier today: see the halfnorm function in the faraway package.
