⚠️There's a newer version (1.4.2) of this package.Take me there.

pastecs (version 1.3.21)

Package for Analysis of Space-Time Ecological Series

Description

Regularisation, decomposition and analysis of space-time series. The pastecs R package is a PNEC-Art4 and IFREMER (Benoit Beliaeff ) initiative to bring PASSTEC 2000 functionalities to R.
