Indexing in anova summary output of the form: summary(aov(y ~ x1, Error = (x1/x2)))
...it under this
framework). There does appear to be some indexing in the output of this
type, but perhaps not enough to obtain single values? Here's what I've
been able to do so far with some example code:
> density.aov<-aov(density ~ substrate + Error(substrate/tile))
>
> anov1<-(summary(density.aov))
> print(anov1)
Error: substrate
Df Sum Sq Mean Sq
substrate 2 1282.4 641.2

Residuals 27 225.700 8.359
Error: Within

repost: problems with lm for nested fixed-factor Anova (ANOVA I)
...different experiments.
I have 48 levels of the main factor x1 and 242 levels of the nested
factor z1, and continuous response variable y1 with around 15.000 data
points. There is no interaction between specification of the main factor
and nested factor levels.
When I run lm on using nested design
anov1=lm(c(as.vector(y1))~as.factor(x1)+ as.factor(x1)/as.factor(z1))
I get a warning
summary(anov1)
Coefficients: (.. not defined because of singularities). I obtain
interaction between factors that should not be included because of the
nested design. Furthermore, the running time takes more than 7...

error when using logistic.display within a loop
...in eval(expr, envir, enclos) : y values must be 0 <= y <= 1". All the response variables have value of 0 or 1. It worked well for summary and anova but not for logistic.display in the loop.
Thanks for any help,
Tom
