  neigb = "gaussian")

Arguments

dataSet	List, data set object generated by MS_to_MA function.
analSet	List, containing the results of statistical analysis (can be just an empty list).
x.dim	An integer specifying the x-dimension of the map.
y.dim	An integer specifying the y-dimension of the map.
initMethod	A character string specifying the initializing method. The following are permitted: "sample" uses a random sample from the data; "random" uses random draws from N(0,1); "linear" uses the linear grids upon the first two principle components directin.
