# S3 method for lisa
plot(x, neigh.mean = FALSE, add = FALSE, inches = 0.2, ...)an object of class "lisa", usually, as a result of a call to lisa.
If TRUE, size of symbols represents average observation in each neighborhood; If FALSE, size of symbols represents the original observation
If TRUE, a lisa-plot will be added to a pre-existing plot.
scales the size of the symbols
other arguments
A bubble-plot of observations against spatial coordinates is produced. Above mean values are signified by red circles. Below mean values are signified by black squares.
If a permutation test was performed, observations for which the associated LISA statistic is significant at a nominal (two-sided) 5%-level will be represented by filled symbols and non-significant values by open symbols. Thus spatial hot-spots are represented by red filled circles and cold-spots by black filled squares.
