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

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
