I am having a problem analyzing some data from a recent experiment in R.
The experiment was balanced with 5 replicates in each group. It included two factors (plant type and leaf age) with 15 combinations (5 plant types x 3 age classes within each plant type).
I arranged the data in long form and conducted a two way ANOVA in R. The main effects were separately significant, but the interaction of both was not.
Now I am unsure what my next steps are.
I want to display my results in boxplots showing which plant types have significant differences, and which leaf ages are significantly different?
