plot.localgauss: Local Gaussian correlation plot

In localgauss: Estimating Local Gaussian Parameters

Description

Plots estimates of local Gaussian correlation.

Usage

## S3 method for class 'localgauss'
plot(x,...,plot.text=TRUE,plot.points=FALSE,tsize=3,
  lowcol="cyan",highcol="magenta",point.col="black",
  point.size=NULL,xlab="",ylab="",divergent.col.grad=T)
     

Arguments

x	S3 object of class "localgauss" produced by the localgauss-function
...	Not used.
plot.text	If TRUE, the numerical values of the estimated local correlation are added to each tile.
plot.points	If TRUE, the original observations are overlain.
tsize	The font size used if plot.text is TRUE
lowcol	The color used to indicate negative correlation of -1
highcol	The color used to indicate positive correlation of 1
point.col	The colour used for observations points if plot.points is TRUE.
point.size	The size of observations points if plot.points is TRUE.
xlab,ylab	The label of x-axis and y-axis, respectively.
divergent.col.grad	If TRUE, a divergent color gradient between lowcol and highcol with 0 as midpoint is used. If FALSE a ordinary color gradient between lowcol and highcol is used.
