Hello.
Recently SpatiaLite 4.0 was released. It has lots of powerful, fast and robust functions for Geoprocessing(spatial queries, overlay analysis, creating topology, network analysis, gridding, creating TIN/voronois).
Some people say SpatiaLite is one of candidate to next standard spatial data format.
Current rgeos package seems to be slower and unstable for bigger spatial data.
And I think if using SpatiaLite, spdep could create spatial weight matrices more speedy than current ones. If this, R will be exactly "R as a GIS".
Unfortunately SQLiteMap, R package for accessing SpatiaLite, has been removed from CRAN since this September.
Any plan to employing this SpatiaLite for current R-geo packages.
Thanks in advance.
