In the following plot, we use linearity.check = TRUE argument to split the data by the level of the moderator \ (W\) and plot predicted lines (black) and a loess line (red) within each group. The predicted lines come from the full data set. Start by downloading R and RStudio. Then open RStudio and click on File > New File > R Script.
