Description

This function uses the maps package to display dots for each incident on a map of a given state over a given year. It takes as inputs the state, represented by its number with all states ordered alphabetically, and year. The filter function from the dplyr package is used to consolidate the data

Arguments

state.num	an integer from 0 through 51, representing each state and the District of Columbia
year	An integer representing a year that is 2013, 2014, or 2015
