I posted this question several days ago, but did not get any answer until now. Since I still have no clue about the source of this error message, I repost a description of the problem including some code:
A student at our institute fitted an aov model, 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 valuesThe 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 0.2020649Her data set and the model are as follows:
Data: http://www.bot.unibas.ch/~pascal/ParzJan.csv
Model (I don't understand the model, but that's not the issue here)
p <- read.csv("ParzJan.csv",header=T)
p.aov <-aov(terms(JI~SP+Ex+Neig+pH+K/G+H+D+tN+br+aN:br+tN:D

+ aN:br:H, keep.order=T), data=p)Any help regarding the source of this plot() error message is appreciated.

P.S.: She used R 1.7.1 on a Mac, but the problem was reproducible on R 1.8.1 under Linux.
