hello... I am trying to develop an analysis similar to the proposed by Urban and Keitt (2001) for connectivity between patches in a landscape. To do that, my first problem is to convert the raster map, into a graph (with area of the patch as an attribute for the node, and the distance between patches as the attribute for the edge). Do you know of any function that can allow me to convert the raster map and create the graph? and a package to realize such kind of analysis? Thanks in advance
