extract_make_stats19

This function extracts the make from a generic make/model string, handling multi-word makes.

Work with and download road traffic casualty data from Great
Britain. Enables access to the UK's official road safety statistics,
'STATS19'. Enables users to specify a download directory for the data,
which can be set permanently by adding `STATS19_DOWNLOAD_DIRECTORY=/path/to/a/dir`
to your `.Renviron` file, which can be opened with `usethis::edit_r_environ()`.
The data is provided as a series of `.csv` files.
This package downloads, reads-in and formats the data, making it suitable
for analysis. See the stats19 vignette for details. Data available from
1979 to 2025. See the official data series at
<https://www.data.gov.uk/dataset/cb7ae6f0-4be6-4935-9277-47e5ce24a11f/road-accidents-safety-data>.
The package is described in a paper in the Journal of Open Source Software
(Lovelace et al. 2019) <doi:10.21105/joss.01181>.

for examples of how the data can be used for
methodological and empirical research.
