Hello. Sp package has grid & grid topology classes. It seems to use them to be able to implement famous map algebra(or cartographic modelling). Any plan to implement this analysis method to sp package? Regards.

Yes, but not in sp. We're even a bit further than plans, but not exactly that much. I just read that in https://stat.ethz.ch/pipermail/r-sig-geo/2004-December/000285.html I wrote 12 months ago about these plans. Indeed, we now have sp on the rails, and should move on. Thanks for reminding me. Many of the point, global and areal operations can be done using standard R syntax; it is however the true spatial functions like spreads and the window functions that would be nice to have. -- Edzer
