plot.lisa.nc: Plots multivariate local indicators of spatial association

Description

`plot' method for class "lisa.nc".

Usage

"plot"(x, ctr = FALSE, add=FALSE, inches=0.2, ...)

Arguments

x
an object of class "lisa.nc", ususally, as a result of a call to lisa.nc.
ctr
if TRUE correlations will be centered before plotting (zero-sized symbols represents the average correlation), if FALSE the observed correlations are used (zero-sized symbols represents zero within neghborhood correlation)
add
if TRUE, a lisa-plot will be added to a pre-existing plot
inches
scales the size of the symbols
...
other arguments

Value

A bubble-plot of the multivariate LISA against spatial coordinates is produced. Negative (or below mean) within-neghborhood correlations are signified by squares. Positive (or above mean) values are signified by circles.If a permutation test was performed, values significant at a nominal (two-sided) 5%-level will be respresented by filled symbols and non-significant values by open symbols. Thus areas of significant positive (or above-average) correlation have filled red circles and areas of significant negative (or below-average) correlation have filled black squares
