I need to represent some data in a very specific way. Right now I have a factor "treatment" with 8 levels, and then for each level, 4 different values obtained in the experiment (let's call it "type" factor with levels c("a", "b", "c", "d"). I would like to represent a graph where I have all "treatment" levels with position dodge for "type""a" and "b", and then I would like to stack "c" and "d" together.
I've tried to implement this solution with no success.
What I have
What I want
I'm pretty sure it's not gonna be possible to have it exactly like I need, but I can accept a close enough try.
Thanks! J.
