spacetime (version 1.3-1)

ST-class: Class "ST"

Description

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

Usage

ST(sp, time, endTime)

Objects from the Class

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

Slots

sp:

Object deriving from class "Spatial"

time:

Object of class "xts"

Methods

[[

signature(obj = "ST"): retrieves the attribute element

$

signature(obj = "ST"): retrieves the attribute element

[[<-

signature(obj = "ST"): sets or replaces the attribute element

$<-

signature(obj = "ST"): sets or replaces the attribute element

% \item{plot}{\code{signature(x = "Spatial", y = "missing")}: plot method % for spatial objects; does nothing but setting up a plotting region choosing % a suitable aspect if not given(see below), colouring the plot background using either a bg= argument or par("bg"), and possibly drawing axes. } % \item{summary}{\code{signature(object = "Spatial")}: summarize object}

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
