Diagram the Final Model

To help visualize our new WAIS-III model, we can use the semPlot library to create a picture of the three-factor model. You will want to include labels and shading to accent the strongest paths in the model, which helps visualize the manifest variables that are best at measuring the latent variable.

Instructions

100 XP
  • Load the semPlot library.
  • Include the standardized loadings as labels with whatLabels and shading with what.
  • Shade the diagram in black in the edge.color argument.
