Hello. I think it's good idea for R to use SpatiaLite instead of dealing with shapefiles directly.
SpatiaLite has functions of Raster GIS and routing, so these functions will enrich spatial analyses in R. It'll be better SQLite/SpatiaLite embedded within R as internal DB. I hope some day R will be running with SpatiaLite and Grass GIS on iPhone, Android and Nokia 900 for field working.
