plot.lisa.nc: Plots multivariate local indicators of spatial association
Description
`plot' method for class "lisa.nc".
Usage
## S3 method for class 'lisa.nc':
plot(x, ctr = FALSE, \dots)
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)
...
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
