plot_centres: Plot centres

Description

This function plots various centre of a set of point observations.

Usage

plot_centres(plotnew=FALSE, plotSDE=FALSE, xaxis="Easting (m)", yaxis="Northing (m)",
robject=NULL, plotweightedpts=FALSE, weightedpts.col='black', weightedpts.pch=19, 
plotpoints=TRUE, points.col='black', points.pch=1, plotcentre=FALSE, centre.col='black', 
centre.pch=19, plotcentral=FALSE, central.col='green', central.pch=19, 
plotCF2PTS=FALSE, CF2PTS.col='orange', CF2PTS.pch=19, plotmedian=FALSE, 
median.col='blue', median.pch=17, plotCMD=FALSE, CMD.col='red', CMD.pch=17, ...)

Arguments

plotnew

Boolean: Set to TRUE to create a new plot. Set to FALSE to overlay current plot.

Boolean: Set to TRUE if the centres for the SDE are to be plotted

xaxis

A string to label the x-axis of the plot

yaxis

A string to label the y-axis of the plot

robject

plotcentre

Boolean: Set to TRUE if the mean/weighted/user-defined centre is to be plotted

centre.col

Specify a colour for the centre

centre.pch

Specify a plotting symbol for the centre

plotcentral

Boolean: Set to TRUE if the central feature is to be highlighted

central.col

Specify a colour for the central feature

central.pch

Specify a plotting symbol for the central feature

plotCF2PTS

Boolean: Set to TRUE if the central feature between 2 point patterns is to be highlighted

CF2PTS.col

Specify a colour for the central feature

CF2PTS.pch

Specify a plotting symbol for the central feature

plotmedian

Boolean: Set to TRUE if the median centre is to be plotted

median.col

Specify a colour for the median centre

median.pch

Arguments to be passed to graphical parameters

Details

The results object, for example, r.SDD object (generated in calc_sdd function) is required to plot the centres for the SDD.

Examples

xaxis="Easting (m)", yaxis="Northing (m)",
weightedpts.col='black', weightedpts.pch=19, plotpoints=TRUE, 
points.col='black', points.pch=1, plotcentre=FALSE, centre.col='black', 
centre.pch=19, plotcentral=FALSE, central.col='green', central.pch=19, 
plotCF2PTS=FALSE, CF2PTS.col='orange', CF2PTS.pch=19,
plotmedian=FALSE, median.col='blue', median.pch=17, plotCMD=FALSE, 
CMD.col='red', CMD.pch=17)

## plot_centres by default takes as input the result produced from CF, CF2PTS, and CMD, read from the current workspace.
