First we need to create the filename for a given accident data.

#get filename
fname <-make_filename(2013)
fname
file.path("..","data",fname)

Next we can read in a single data set using the file name we just created. Each row of the data represents a single accident.

df <- fars_read(fname)
head(df)

If you need to read in multiple years just use fars_read_years. In the following example only 2013 and 2014.

fars_read_years(2013:2014)

Now to get the summary of the counts by year we can use the following function.

fars_summarize_years(2013:2014)

Lastly we will plot map of accidents for California using fars_map_state

fars_map_state(state.num=6, year=2013)
