Re: [R] R^2 from lme function Hi Martin, many thanks for your tip! but,                                        { :-(   } what it 'full MLE' ?   how to calculate? it is a saturated model??? and it is valid for 'no-intercept model? Many thanks again... Cleber > Hi Cleber, > I have been using this function I wrote for lmer output. It should be  > easy to convert to lme. As with everything, buyer beware.
