How to use plotInteraction?

Hi,

I am trying to use the function plotInteraction. I am using Matlab R2018A. In the docs it says it has been introduced in R2012b but I still don`t have it. What could be a potential reason for that?

Thanks!

This function is in Statistics and Machine Learning Toolbox. Do you have this toolbox installed? Check the output of the ver function.

This function requires its first input to be either a LinearModel or CompactLinearModel object. If you're trying to call it with a regular double matrix as the first input, that will not work.

Hi, thanks for your answer. I do have it installed (version 11.3). Matlab still says the function is 'undefined'
