Modeling Non-Continuous Linear Responses of Ecological Data

Tools for modeling non-continuous linear responses of ecological communities to environmental data. The package is straightforward through three steps: (1) data ordering (function OrdData()), (2) split-moving-window analysis (function SMW()) and (3) piecewise redundancy analysis (function pwRDA()). Relevant references include Cornelius and Reynolds (1991) and Legendre and Legendre (2012, ISBN: 9780444538697).

segRDA

SegRDA provide functions for performing a piecewise redundancy analysis. This package is designed for (1) ordering the target data, (2) identifying the breakpoints using a spli-moving analysis and (3) performing a piecewise regression.
