wql: Exploring Water Quality Monitoring Data

Functions to assist in the processing and exploration of data from environmental monitoring programs. The package name stands for "water quality" and reflects the original focus on time series data for physical and chemical properties of water, as well as the biota. Intended for programs that sample approximately monthly, quarterly or annually at discrete stations, a feature of many legacy data sets. Most of the functions should be useful for analysis of similar-frequency time series regardless of the subject matter.

The main purpose of 'wql' is to explore seasonal time series through plots and nonparametric trend tests. It was created originally to examine water quality data sets (hence, "wql") but is suitable as a more general purpose set of tools for looking at annual or seasonal time series.wql-package wql
