Hi, I would like to make a plot of the US states (or lower 48) that are
colored based upon a percentage change column. Ideally, it would gradually
be more blue the larger the positive change, and more red the more negative
is the change.
The data I have looks like:
State Percent.Change
1 Alabama 0.004040547
2 Alaska -0.000202211
3 Arizona -0.002524567
4 Arkansas -0.008525333
5 California 0.001828754
6 Colorado 0.011116150
I have read help for the maps library and similar plots online but can't
grasp how to map the percentage.change column to the map. thank in advance,
Michael Bailey
