Usage

## S3 method for class 'lisa.nc'
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.
