Investigate the air quality of two areas in California. Use the base plotting functions from the graphics package. Show the code you used to generate the graphs. Use the data in AirQualitySanFranciscoData.csv and in AirQualitySanDiegoData.csv. Create four graphs with the year on the horizontal axis. Two of the graphs have number of days ppm exceeded the standard on the vertical axis. Two of the graphs have maximum concentration on the vertical axis. Notice the spacing between the columns of graphs. Make an exact replica of the graph shown below:
