Hi,
I'm looking for a way to find the largest circle fitting in an irregular 
polygon. This is not the real definition of an incircle (as it has to be 
tangent to all edges, but it's a more synthetic title).
Spatstat package has an incircle function, but designed for an owin 
class object. Before trying to adapt the function to my needs, so I can 
input a shapefile, I would be happy to get some advices (if any 
available), or another package to look at.

Thanks,
Etienne
