Description Usage Arguments Details Value Examples

The fars_read_years() function is used to read in FARS data for a specified range of years.

1	fars_read_years(years)

years

A year or a vector of years (in any class that can be coerced to numeric) to specify which FARS reports are to be read in

The function internally uses the make_filename function to create standardised file names from the years input. It then reads in CSV files from the working directory that correspond to this standardised file name and uses dplyr functions to reorganise the data.

This function returns a list of FARS data where every list entry contains the data for one of the years specified in form of a tbl_df. The data frame has one line for every data point in the respective FARS data set and indicates the month and the year for this data point.
It produces an error warning if an invalid year is given as input.
