Adjusted p-values with TukeyHSD (patch)
...e="Tukey"))
Here I got:
[1] 0.09 0.01 0.10 0.00 0.00
[1] 26.87 0.03 27.10 0.00 0.00
For a small number of contrasts they're equivalent, for example:
data(warpbreaks)
fm1 <- aov(breaks ~ wool + tension, data = warpbreaks)
tHSD <- TukeyHSD(fm1, "tension", ordered = FALSE)
print(tHSD)
mcHSD <- simint(breaks ~ wool + tension, data = warpbreaks,
whichf="tension", type="Tukey")
summary(mcHSD)
I also attached the complete function (mTukey...

Multiple comparison and two-way ANOVA design
Dear useRs,
I'm working on multiple comparison design on two factor (2 3 levels)
ANOVA. Each of the tests I have tried (Tukey, multcomp package) seem to
do only with one factor at a time.
fm1 <- aov(breaks ~ wool * tension, data = warpbreaks)
tHSD <- TukeyHSD(fm1, "tension", ordered = FALSE)
$tension

Physically extracting P-value from TukeyHSD test output
Hey,
I have this TukeyHSD output from which I would like to extract only the
P-values (p adj, last number).
The problem is that the test output is a character list.
How can I "break" this sentence to separate the Pv?

In case it helps:
