I want to plot an interaction in R, but I get a quite confusing plot that does not appear parsomonious at all.
The code I used to create it is:
interaction.plot(x.factor = mydata$cN, trace.factor = mydata$cDA, response = mydata$tDep)
Could it maybe be a problem with graph scalling? What do you think it could be? How could I make the interpretation of this plot easier?
