permute - Functions for Generating Restricted Permutations of Data

A set of restricted permutation designs for freely exchangeable, line transects (time series), and spatial grid designs plus permutation of blocks (groups of samples) is provided. 'permute' also allows split-plot designs, in which the whole-plots or split-plots or both can be freely-exchangeable or one of the restricted designs. The 'permute' package is modelled after the permutation schemes of 'Canoco 3.1' (and later) by Cajo ter Braak.

cocorresp - Co-Correspondence Analysis Methods

Fits predictive and symmetric co-correspondence analysis (CoCA) models to relate one data matrix to another data matrix. More specifically, CoCA maximises the weighted covariance between the weighted averaged species scores of one community and the weighted averaged species scores of another community. CoCA attempts to find patterns that are common to both communities.

temporalEF - Temporal Eigenfunctions

Build sets of (asymmetric) one-dimensional, temporal eigenfunctions. The set of eigenfunctions are orthogonal patterns of temporal variation at a range of scales. Two types of temporal eigenfunctions are implemented; i) asymmetric temporal eigenfunctions (ATEs), based on the Asymmetric Eigenvector Map (AEM) method of Blanchet et al (2008), and ii) principal coordinates of temporal neighbour matrices (PCTNs), based on the concept of principal coordinates of neighbour matrices.
