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.
Regards.
