Usage

fars_read(filename)

Arguments

filename

A character vector giving the location of the data file to be imported.

Details

The tbl_def function returns a tibble otherwise execution of the function stops and a warning ' file accident_xxxx.csv.bz2 does not exist' is issued (where xxxx is the year of data being imported). The suppressmessages function is used to ignore all simple diagnostic messages.

Value

A 50 column tibble with each row representing a fatal incident.

Note

The readr and dplyr packages must be installed in the R environment but do not have to be attached.
