AQEval: R code for the analysis of discrete change in air quality time-series

This is the authors' abstract. We don't add key points for this paper.

AQEval (Air Quality Evaluation) is an R package for the routine investigation of discrete changes in air quality time-series.The main functions, quantBreakPoints and quantBreakSegments, use a three-step method to find possible 'points-of-change', test these and quantify the most likely 'points-of-change' or 'regions' about them.Other key functions build on these to provide a workflow to measure smaller changes and/or changes in more complex environments.
