Whether you are an environmental scientist, a pollution expert or just concerned about the air you breathe when cycling in the United Kingdom, the ropensci rdefra package can help find the information you need. This package gives you access to the UK-AIR database, hosted by the Department for Environment, Food & Rural Affairs in the United Kingdom, directly from R. The database comprises hundreds of air quality monitoring sites and each provides time series of concentration for different pollutants such as ozone, carbon dioxide and nitrogen oxides amongst others. It allows you to efficiently download, plot and compare data for multiple years/stations so that you can easily carry out spatio-temporal analysis or simply plan an healthier route for you bike ride. The package is fully documented and the vignette contains examples for a number of applications, such as how to generate the interactive map of the monitoring stations (see screenshot below).
