Mar 29 18:10:18 iansimac.gateway rsession[69550] <Error>: Error: this
application, or a library it uses, has passed an invalid numeric
value (NaN, or not-a-number) to CoreGraphics API. 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,
