Dear all, I have just uploaded to CRAN the version 1.4 of the package 'adehabitat'. Significant changes are listed below: - The eigenanalysis of selection ratios (Calenge and Dufour, 2006, Ecology) can now be performed using the function eisera(). It can be used for the analysis of habitat selection when habitat can be considered to consist of several habitat types (e.g. vegetation types). - A new class, the class "ltraj", is now available for the...

...great work of Paolo Cavallini (Faunalia). It is available at: https://www.faunalia.it/animove/trac/ Any other project intended to manage, store, analyze animals movements can be added there, provided it is free and open source. * Note that my e-mail adress has changed.
