[postgis-users] Postgis & R language

[Jan Hartmann]

You could do this completely within R by installing both rgdal and 
rpostresql (http://code.google.com/p/rpostgresql/). You'll have to split 
your queries in an attribute part (rpostgresql) and a geometry part 
(rgdal, returning sp items) and combining them afterwards. I have never 
done this but it should work. Moreover, one of the developers of 
rpostgesql is Joe Conway, the maker of PL/R. He'll certainly anser 
questions on the PL/R mailing list.
