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

Dear Malcolm, I don't think that anyone fielded this question earlier today: see the halfnorm function in the faraway package. I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox --------------------------------
