Exercise 4a

Start reviewing the materials related to getting started with R (see above). Create two simple plots (they do not have to be maps) of any topic you want.

Export the plots as a JPEG and then create a page describing what you did in either a ex4a.md or ex4a.html page linking to the images.

These plots are for Iowa Crashes that the data reference is “https://data.iowadot.gov/datasets/IowaDOT::crash-data-sor/about”

Plot 1

For the first plot I grouped the data by CRASH_YEAR and calculate the sum of each injury type.

Plot 2

For the second plot I created a histogram of fatalities, colored by CRASH_YEAR and split by DRUGALCREL.
