Spatial autcorrelation

This function is a wrapper around lisa.nc to calculate spatial autocorrelation of a spectral map.

spatial_ac(x, neigh = 2, colname = "spatial_ac", ...)

Arguments

x	a hyperSpec object.
neigh	neighborhood size as defined in lisa.nc.
colname	name of the data column to be added to x@data, containing the mean correlation within the neighborhood.
...	additional arguments handed further to lisa.nc.

Value

a hyperSpec object such as given for x with an additional column in x@data.
