The utility of common scaling and individual titles

The plots you generated in the previous exercise showed that the four Anscombe quartet datasets have very different appearances, but a careful examination of these plots reveals that they exhibit different ranges of x and y values.

The point of this exercise is to illustrate how much more clearly we can see the differences in these datasets if we plot all of them with the same x and y ranges. This exercise also illustrates the utility of improving the x- and y-axis labels and of adding informative plot titles.

Examine the range of x and y values from the previous four plots to determine a common range that covers the ranges of all four of these plots.
Set up a two-by-two plot array using the par() function.
Plot the y1 variable against the x1 variable using these common ranges, with x-axis label "x value" and y-axis label "y value", and use the main argument to add the title "First dataset".
Repeat for the other three Anscombe data pairs, adding the appropriate titles.
