This vignette provides an overview of the farsdata package. This package consists of 3 main and 2 helper functions designed to make using the Fatality Analysis Reporting System a little easier

Package Functions

the 3 main functions are the following

"fars_read_years" allows you to read the csv data for one or more years. The data is returned as a summarized list with one dataframe per input year. Invalid years or years with no value will return NA as that list element

setwd(system.file("extdata", package = "farsdata"))
data <- fars_read_years(c(2013,2014))

"fars_summarize_years()" takes a vector of the years to query and returns a dataframe consisting of summarized monthly data by year

setwd(system.file("extdata", package = "farsdata"))
data <- fars_summarize_years(2013:2015)

"fars_map_state()" takes the summarized data and returns a plot for a given state index and year. The index must map to an index in the dataset

setwd(system.file("extdata", package = "farsdata"))
data <- fars_map_state(5,2014)

The datafile needs to be available in the extdata path in the project
