In xzguqgsntdzq/Review_2: Plotting and summarising FARS data

farsReport

The goal of farsReport is to allow easy reporting of standard formatted FARS accident reports.

The package contains data from the US National Highway Traffic Safety Administration's Fatality Analysis Reporting System, which is a nationwide census providing the American public yearly data regarding fatal injuries suffered in motor vehicle traffic crashes. The package allows easy reporting of FARS data sets from 2013, 2014 and 2015.

Installation

You can install the released version of farsReport from GitHub with:

devtools::install_github("https://github.com/bsleczko/farsReport")

FARS reporting

The farsReport package provides two functions for FARS reporting, the first is returning a tibble summarising the FARS for specified set of years, the second is plotting the FARS accidents on the map of the specified state, for specified year.

FARS summary

The fars_summarize_years(years) function summarizes the FARS accidents per month and year, for given set of years.

library(farsReport)
farsReport::fars_summarize_years(years = c(2013, 2014))
#> # A tibble: 12 x 3
#>    MONTH `2013` `2014`
#>    <int>  <int>  <int>
#>  1     1   2230   2168
#>  2     2   1952   1893
#>  3     3   2356   2245
#>  4     4   2300   2308
#>  5     5   2532   2596
#>  6     6   2692   2583

FARS mapplot per state

The fars_map_state(state.num, year) function will plot FARS accidents for specififed year on border map of the state (specified by state.num parameter). This function does not return any data, the side effect of the function is the plot of FARS accident on the border map of the state.

library(farsReport)
farsReport::fars_map_state(state.num = 13, year = 2014)
