spate.plot: Plot a spatio-temporal field.

In spate: Spatio-Temporal Modeling of Large Data Using a Spectral SPDE Approach

Plot a spatio-temporal field.

Description

Generates a figure or an animation of a spatio-temporal field.

Usage

spate.plot(xi,nx=NULL,whichT=NULL,format="ImgTogether",ToFile=FALSE,path=NULL,
           file=NULL,indScale=FALSE,main=NULL,mfrow=NULL,
           imagesize=c(1000,1000),zlim=NULL,breaks=NULL,...)

Arguments

xi	A spatio-temporal field stored in an T x N matrix with columns and rows corresponding to time and space, respectively.
nx	Integer specifying the number of points on the x-axis. If 'NULL', a quadratic grid is assumed.
whichT	Vector of integers specifying the time points that are plotted. If 'NULL', all time points are plotted.
format	A string specifying how the spatio-temporal field should be ploted. "ImgTogether" produces one single plot containing all spatial fields at all time points. With "ImgSeparate", the spatial fields at each time point are plotted in separate plots.
ToFile	Indicates whether the output should be saved to a file.
path	Path indicating where to save the file.
file	File name.
indScale	Indicates whether the color scale for the spatial plots is the same for all time points (indScale=FALSE) or separate for each time point (indScale=TRUE).
main	Titles for the plots. Can be either be NULL or a character vector of length equal to the number of time points or 1.
mfrow	See 'par'. Can be either NULL or an integer vector of length two. If it is NULL, the functions determines mfrow automatically.
imagesize	The size of the .jpeg image if ToFile=TRUE.
zlim	Graphical parameter to be passed to 'image'. Determines the scale on the z-axis of the plots. If 'indScale=FALSE' one can specify the common scale on the z-axis of the plots through this argument.
breaks	Graphical parameter to be passed to 'image'.
...	Other graphical parameters that are passed to 'image' and 'par'.

Value

Plots illustrating a space-time field.
