R code for creating graphs to track the progress of using Food Hygiene Rating Scheme data to improve OpenStreetMap. See the wiki page for more details.
The code uses the CSV files created by the FHRS/OSM comparison tool. The combine.sh script reads any stats-*.csv files in the same directory as the script and its output can be redirected (e.g. combine.sh > combined.csv) to create a single CSV file to be read by R.
