I?m a novice and this message looks like it shouldn?t be ignored. Someone who knows what they?re doing should probably take a look. Thanks Ian Lester

This is a serious error and contributes to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.
Please make your examples *reproducible* as the posting guide requests. I *presume* that your data are the "fat" data from the "UsingR" package, which you did not mention. After installing and loading "UsingR" I did > logfat.lm <- lm(body.fat~log(BMI),data=fat) > plot(logfat.lm) and got a sequence of plots, with no error thrown. It would appear that whatever is causing the error that you saw is peculiar to your system. cheers, Rolf Turner
