But keep in mind that if algorithms are changed, there is nothing left from "old" homerange plugin, and the new one will require a different name. > > Sextante already collaborates very well with R, without needing > > rpy2, so my idea is to rewrite the plugin in a way that well-tested > > R algorithms are still used. > nice > > My estimate is of a week of work, in order to migrate all > > functionality and provide a user-friendly suite of tests that will > > help users in isolating plugin errors. > I do not think the rewrite of kernels should take more than two days, > so efforts are comparable. It took much more time for Clément to write a stable, reliable set of algorithms in R.

I am willing to help in solving present problems, so any robust decision on the implementation has my support. > all the best, and thanks for your thoughts.
