This is the vignette for the 'farsAssignment' package.

The FARS (Fatality Accident Reporting System) data collected by the NTSE provides records fatal accident reports for a given year. The tools in this package enable reading, summarizing and plotting the FARs data for one or several years. The package also includes three years of FARS data.

FARS data

Each of the FARS data files is in "comma separated value" format. Any of these data sets can be loaded with fars_read() as a data.frame (actually, a tbl_df). The data sets available in this package are:

accident_2013.csv.bz2
accident_2014.csv.bz2
accident_2015.csv.bz2

The NHTSA Fatality Analysis Reporting System data is described here The data contains 50 variables with column names as below:

setwd("..")
source("R/fars_functions.R")
setwd("..")
farsDF2014 <- fars_read(make_filename(2014))
colnames(farsDF2014)

FARS functions

make_filename(year) will generate a file name in the appropriate format (e.g. "accident_[year].csv.bz2"")
fars_read(filename) will return a tbl_df data.frame of the observations for the given year
fars_read_years(filenames) will return a list of tbl_df data.frames with only the month and year retained for each fatality report
fars_summarize_years will report, by year and month, the number of reports.
fars_map_state(state.code, year) wil plot the accident report locations for a give state.code.
