Using the Year Dataset that you need

This function takes a list of years for FARS dataset and convert it to the tidy dataset with additional column of the year.

years <- c(2013:2014)
filtered_data <- fars_read_years(years)

Plot Fatal accident locations

This function fars_map_state() use the object class created by the fars_read_years() function as arguments and returns a plot of the state with accident locations. The state indices need to correspond available indeces from the dataset. Here are some examples:
