Egzersiz talimatları

  • Add a geom_smooth() layer to add a fitted linear model using the "lm" method.
  • Set the scales to be "sliced".
  • With the linear model layer added to the plot, specify that automatic cognostics should be computed for this display and explore what new cognostics this layer adds to the display.
