spacetime : Spatio-Temporal Data in R

Abstract

This document describes classes and methods designed to deal with di⬚erent types ofspatio-temporal data in R implemented in the R package spacetime, and provides examplesfor analyzing them. It builds upon the classes and methods for spatial data frompackage sp, and for time series data from package xts. The goal is to cover a number ofuseful representations for spatio-temporal sensor data, and results from predicting (spatialand/or temporal interpolation or smoothing), aggregating, or subsetting them, andto represent trajectories. The goals of this paper are to explore how spatio-temporal datacan be sensibly represented in classes, and to ⬚nd out which analysis and visualisationmethods are useful and feasible. We discuss the time series convention of representingtime intervals by their starting time only. This vignette is the main reference for the Rpackage spacetime; it has been published as Pebesma (2012), but is kept up-to-date withthe software.
