WebPlot function in R The R plot function allows you to create a plot passing two vectors (of the same length), a dataframe, matrix or even other objects, depending on its class or the input type. We are going to simulate two random normal variables called x and y and use them in almost all the plot examples. Sample data WebThe ‘Scale-Location’ plot ( which=3 ), also called ‘Spread-Location’ or ‘S-L’ plot, takes the square root of the absolute residuals in order to diminish skewness ( \sqrt { E } ∣E ∣ is much less skewed than E ∣E ∣ for Gaussian zero-mean E E ).
