Problems to extract data from anova table
Hi,
this is my script

> results <- summary(anova$Within)
this is results

extraction of mean square value from ANOVA
Hello,
I am randomly generating values and then using an ANOVA table to find the
mean square value. I would like to form a loop that extracts the mean square
value from ANOVA in each iteration. Below is an example of what I am doing.
a<-rnorm(10)
b<-factor(c(1,1,2,2,3,3,4,4,5,5))
c<-factor(c(1,2,1,2,1,2,1,2,1,2))
mylm<-lm(a~b+c)
anova(mylm)
Since I would like to use a loop to

adonis (vegan package) and subsetted factors
...evels have any records. Then I run:
> adonis(CoastNear[,5:118]~Habitat, data = CoastNear,permutations=1000,

Call:
adonis(formula = CoastNear[, 5:118] ~ Habitat, data = CoastNear,
permutations = 1000, method = "jaccard")

another aov question: unbalanced multiple responses
Hi,
This question is related to the bwplot issue I reported yesterday. I have a 3 factors (2x3x2) dataset that I collapsed into a 2 factors dataset (3x2 = sizexModality). For size==small, I have 2 observations per subject (Snr), for the other sizes only 1.
I reckoned that aov (and underneath, lm) might handle this as it should, since the subjects are idendified, when I do
> aov(
