In rwpalin/fars: Summarize and plot FARS accident data

fars

Welcome!

The fars package is an example created for a course assignment.

FARS is the US National Highway Traffic Safety Administration's Fatality Analysis Reporting System.

The functions and sample raw data in this package read, summarize and plot accident sites by US state and year/month.

The sample data in the inst/extdata directory covers the years 2013 to 2015. It is as provided in the week 2 assignment (one file per year, in csv.bz2 format). As we only use a small number of variables, I document them in the vignette rather than create a specific help file.

I made two changes to the functions:

• Converted dependent functions to standard evaluation
• Added a system.file call within make_filename to allow tests to access the sample data. A new parameter internal has been added to several functions, which defaults to TRUE (meaning: use sample data, not external data).

The package vignette and function help have further details.

Installation

This package is solely on GitHub and intended for peer reviewers taking the same course, or other valid educational purpose. I hope you learn something from me and thanks for any feedback.

You can install fars from the R console as follows:

devtools::install_github("rwpalin/fars", build_vignettes=TRUE)
