Pastecs (Package for the Analysis of Space-Time Ecological Series) is a R package dedicated to ecological series analysis.

Analysis of Space-Time Ecological Series

Pastecs or "Package for Analysis of Space-Time Ecological Series" is an object-oriented library of functions for R (http://cran.r-project.org). It runs on most platforms (Windows, MacOS, Linux, Unix). It is originally conceived to analyze oceanological data, although it can also be used to compute space-time series in ecology or in other fields.

Initially called Passtec+, the project of converting Visual Basic algorithms implemented in Passtec into a library of functions for R is a PNEC-Art4/IFREMER initiative (Benoit Beliaeff and Frederic Ibanez). It was ultimately renamed Pastecs to avoid conflicting name with other software.

The Pastecs library is entirely written in S language by Philippe Grosjean. It contains a hundred functions to regulate, decompose and analyze uni- or multivariate space-time series.
