Thanks @Purkinje-cell ! Zehua also made a similar fix for scc, and he additionally added a simple method to smooth the spatial constrained cluster by neighborhood major voting. you can test it out #250 |

Spatial constrained clustering code in Spateo is very slow now even for small sparse matrix input. The problem is because when use sparse matrix input, the transformation from matrix to igraph takes a lot of time iterating edges. Directly convert sparse matrix input to dense solved the problem.
I also fixed some bugs in plot functions of the CCI model.
