wq (version 0.4.3)

wq-package: Exploring water quality monitoring data

Description

Functions to assist in the processing and exploration of data from environmental monitoring programs. The name "wq" stands for "water quality" and reflects the original focus on time series data for physical and chemical properties of water, as well as the plankton. The package is intended for programs that sample approximately monthly 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.
