Hi,
Is this what you want?
?TukeyHSD
summary(fm1 <- aov(breaks ~ wool + tension, data = warpbreaks))
tk.fm1<-TukeyHSD(fm1, "tension", ordered = TRUE)
tk.fm1
(tk.fm1[[1]][,4])

Subject: [R] Help with TukeyHSD
Hi
I am conducting ANOVA using the aov function
I am also conducting TukeyHSD to obtain which of the groups show variance
How can I obtain the first three p values from the list below?
>zzz.aov <- aov(Intensity ~ Group, data = zzzanova)
> TukeyHSD(zzz.aov)
Tukey multiple comparisons of means
95% family-wise confidence level
Fit: aov(formula = Intensity ~ Group, data = zzzanova)
$Group
diff lwr upr p adj
Group2-Group1 0.778354812 -3.414233 4.970943 0.9607836
Group3-Group1 -0.734044848 -5.073786 3.605696 0.9698685
Group4-Group1 -0.000158625 -4.192747 4.192429 1.0000000
Group3-Group2 -1.512399661 -5.852140 2.827341 0.7933015
Group4-Group2 -0.778513438 -4.971101 3.414075 0.9607611
Group4-Group3 0.733886223 -3.605855 5.073627 0.9698870
