How to create an interaction plot according to the contrasts I set up?

@noelchiu

A <-- c(-1, 1)
contrasts(B) <-- cbine(c(-2, 1, 1), c(0, -1, 1))

You're going to find it really hard to get help without a reproducible example that contains executable R code:

If you need help, your job is to make it as easy as possible for others to help you. If you’re having problems with R code the most important thing to do is create a minimal reproducible example, or reprex for short. If you’ve never heard of reprexes before, please start at http://www.tidyverse.org/help/#reprex .

If you have code that runs but doesn’t give the right answer, do your best to clearly state what you expected to see. A quick sketch can often be hugely helpful.

Even if you don’t know exactly what you want, a reprex is still helpful - you can use it to sketch out your data and give helpers a running start.
