Fits Modern Analogue Technique and Weighted Averaging transfer function models for prediction of environmental data from species data, and related methods used in palaeoecology.
analogue is an R package for use with palaeoecological data. Originally, analogue was intended as an R implementation of analogue methods such as analogue matching, ROC curves, and MAT transfer function models, and the computation of dissimilarity coefficients. Since then the scope of the package has grown to include a number of other methods applicable to data routinely encountered in palaeoecology and palaeolimnology.
Bug reports and feature requests should be filed as issues.
analogue is released under the GNU General Public Licence Version 2.
V12.122The data were stored as proportions but treated as percentages in examples. To better match the
V12.122was converted to percentages. Reported by Richard Telford #22.
prcurve modified to use package princurve version >= 2.0.2.
join() had a serious bug that caused the columns to be labelled incorrectly when a
type = "left"join was used, if the columns weren't in the same order in the data frames to be merged. Issue #16
Stratiplot() gained argument
labelValues, which allows for custom labelling of variables in a plot. A vector of expressions can be supplied for fancy labelling such as that required for isotopes, equations, sub/superscripts, greek characters, etc.
Climate data set had incorrectly-named columns and was missing some variables. The NAMPD is now updated to version 1.7-3 and the name and missing data issues have been fixed. Reported by Simon Goring in Issue #17.
Stratiplot() now draws a plot on the current device and returns a
"trellis" object invisibly. This fixes #13 and prevents a blank page being drawn in devices such as
Stratiplot() now handles a matrix as argument
x via an S3 method for class
tran() add a
"none" transformation which just returns its input. This is useful if you are writing code and comparing transformations and need to temporarily turn them off.
