I have a matrix of positions returned from any of the igraph layouts, e.g., 

layout=layout.fruchterman.reingold(g)

This just has a set of points:

            [,1]        [,2]
[1,]  22.0952841 -25.0292619
[2,]  14.0612662  13.0353858
[3,]  54.0149021  12.5197793
[4,]  27.5570371 -25.2109356

Does someone know of a collision detection package that I can feed this into and get back similar matrix with points moved so that there is no collisions? (i.e., given some min dist)

  • not quite :(, the preservation (as much as possible) of the original coordinates is needed. – SOUser Feb 24 '15 at 17:08
