Plot method for categorical focal predictors #199

Open strengejacke opened 2 years ago

First, it's difficult to see the point estimate, and second, this plot shows no confidence intervals?

m <- lm(Sepal.Width ~ Petal.Length + Petal.Width + Species, data = iris)
modelbased::estimate_expectation(m, insight::get_datagrid(iris, "Species")) |> plot()

There's no error band because the x variable is discrete. With a discrete focal variable, we should make a recipe like that for estimate_means()

Yes, yes, I know (that's why I added "categorical" in the title), I just wanted to keep this issue in mind, because we have CIs for the predictions, we just don't plot them.

Yep, this is a bug that has bothered me for a while lol

same as #145 ?
