Hello I have performed the following ANOVA test (age = young and old,
tret = non treated and treated):
> ANOVA_EPC<-aov(Dibi ~ age*tret, data = EPC)
> summary(ANOVA_EPC)
Df Sum Sq Mean Sq F value Pr(>F)
age 1 25.346 25.346 2.4510 0.13587
tret 1 5.962 5.962 0.5766 0.45806
age:tret 1 53.280 53.280 5.1522 0.03652 *
Residuals 17 175.800 10.341
---
Signif. codes: 0 *** 0.001 ** 0.01 * 0.05 . 0.1 1
And I can see a significative effect of interaction
What is the Tukey code to see where the interaction is significant?
EPC.TUKEY<-TukeyHSD(ANOVA_EPC)
EPC.TUKEY$ ????
Thank you for your time
