object

a <code>logical</code>, the black and white mode minimal gray value.

value


This generic method intends to extract the black and white mode minimal gray value (from 0 to 1) of a <code>SpatialNetwork</code> object.


Facilitates the rendering of networks for which nodes have a specific position on a map (cities, participants in a political debate, etc.). Map data and network data are stored together in a single object which handles the match between network nodes and their respective position on the map. The plot method renders both the map and the network data. Several networks can be plot simultaneously. The graphic is highly customisable and the legend is automatically printed. Map data have to be supplied as 'SpatialPolygons' objects (from the 'sp' package) and network data as 'named matrix'.
