plotting group means and errors #96

Closed nicholascdove closed 3 years ago

nicholascdove commented 3 years ago

Instead of plotting the estimate and error for individual samples, how should one plot group means and errors? I understand that I can extract group means using the betta function, but I'm unsure of how to extract the error from groups that are not the intercept. I could probably sequentially dummy code the variables, so that each would be the intercept, but I wonder if there is an easier way.

Hi @nicholascdove – sorry for the delay getting back to you. The newest version of breakaway now includes a function, betta_lincom, that will give you means and confidence intervals for arbitrary linear combinations of fixed effects in your model. There's an example given in the discussion of issue 111, and the the hypothesis testing vignette for breakaway (v 4.7.4) also discusses this function. Hope this helps!
