Hi all,
A student at our institute asked me for help with the following problem:
After fitting an aov model, she wanted diagnostic plots, and got the
following error message:
> plot(p.aov)
Hit <Return> to see next plot:
Hit <Return> to see next plot:
Error in plot.window(xlim, ylim, log, asp, ...) :
need finite ylim values
In addition: Warning message:
X11 used font size 8 when 9 was requested
The second plot was not produced. I then tried to produced the plot
manually, which worked, and checked the range of the residuals:
> qqnorm(resid(p.aov))
> range(resid(p.aov))
[1] -0.2428688 0.2020649
She used R 1.7.1 on a Mac, but I reproduced the problem on R 1.8.1 under
Linux.
Any help regarding the source of this problem is appreciated
