analogue-package: Analogue and weighted averaging methods for palaeoecology

Description

analogue is a package for quantitative palaeoecology with a focus on analogue methods, transfer functions, and data handling and display.

Arguments

Analogue methods

analogue provides functions for analogue matching and the modern analogue technique (MAT) via analog and mat. A wide range of dissimilarity coefficients are available via the distance function.

Additional analysis of modern and no-analogue problems is facilitated via a range of functions implementing many methods from the literature. In particular, the receiver operating characteric (ROC) curves method of Gavin et al (2003) is available in roc and a related method employing direct logistic regression modelling (Simpson & Birks, 2012) is available in logitreg.
