In EV201/TestNewPackage: functions for accident stats in the US

TestNewPackage

The goal of TestNewPackage is to test R with Github for the an assignment in the ‘building R packages’ Coursera course.

Installation

You can install the released version of TestNewPackage from CRAN with:

install.packages("TestNewPackage")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("EV201/TestNewPackage")

Accident statistics

The fars functions use the buildin databases: accident_2013.csv.bz2, accident_2014.csv.bz2, accident_2015.csv.bz2 You can access these databases directly by system.file(“extdata”, filename, package = “TestNewPackage”)

The fars functions show a summary of the accidents per month and year (fars_summarize_years()) or the accidents for a year on a map for a state (fars_map_state()). Only the years 2013-2015 can be used.

Examples

library(TestNewPackage)

summarizing accidents for a year:

fars_summarize_years(2013)
#> # A tibble: 12 x 2
#>    MONTH `2013`
#>    <dbl>  <int>
#>  1     1   2230
#>  2     2   1952
#>  3     3   2356
#>  4     4   2300
#>  5     5   2532
#>  6     6   2692
#>  7     7   2660
#>  8     8   2899
#>  9     9   2741
#> 10    10   2768
#> 11    11   2615
#> 12    12   2457

or plotting the accidents for a year on a state map:

fars_map_state(1, 2015)

#> [1] 0
