Question

a. With reference to the lecture slides (Lecture 4), determine the mean center and
standard distance for each of the above points datasets.
b. Create a plot showing the events for each dataset as well as the location of the
mean center and standard distance overlaid on that plot. NOTE: see "symbols()"
for plotting the standard distance and in particular the argument "inches" for that
function and see "points" for plotting the centroid.
