Exercise

Multidimensional scaling in two dimensions

In this exercise, you will perform multidimensional scaling of state.x77 and plot the resulting object locations in a two dimensional space.

Instructions

100 XP

Compute the distance matrix and assign it to an object state.dist.
Compute the multidimensional scaling of the data on the distance matrix.
Use the ggplot() function to plot the representation of the state.x77 data in two dimensions. Color the state names by their region using the vector state.region.
