spacetime (version 1.1-5)

ST-class: Class "ST"

Description

An abstract class from which useful spatio-temporal classes are derived

Usage

ST(sp, time, endTime)

Arguments

sp

an object deriving from class Spatial, such as a SpatialPoints or SpatialPolygons

time

an object of class xts, or a time vector (currently: Date, POSIXct, timeDate, yearmon and yearqtr; are supported; see xts); in the latter case, it should be in time order

endTime

vector of class POSIXct holding end points of time intervals

Objects from the Class

Objects of this class are not meant to be useful; only derived classes can be meaningful

Examples

time = as.Date('2008-01-01')+1:2
library(sp)
sp = SpatialPoints(cbind(c(0,1),c(0,1)))
ST(sp, time, delta(time))
