Source data
Source data must be in columns as: [X] [Y] [Code] representing points or polygon centroids of different categories. Every object in a separate row, column separator can be either space, tab or semicolon, decimal separator can be either point or comma. Lines beginning with a acharacter (headings) are removed. Source data can be poFrequencies of categories being the nearest neighbours are calculated.
