I’m using ggeffect/ggpredict/ggemmeans to plot interaction effects.
I have a categorical factor variable with three levels (0,1,2). When I use “connect lines = TRUE” the default connects the dots in numerical order, i.e. 0->1 and 1->2. But I want the lines to be connected in relation to the reference level (0), i.e., 0->1 and 0->2
How to adjust the default? This is my simple code:
X <- ggemmeans(mymodel, terms = c("COMP", "LOC"))
plot(X, connect.lines = TRUE)
Attached picture shows what I get vs what I want. I think my question is simple enough that a reprex is not necessary)
