Hi David, You can use PL/R to access R functionality from a Postgres SQL command line, or you can use rgdal to read Postgis data into R.
So it depends on whether you want to work in the DB & add R capabilities, or work in R & access Postgis data. See: http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgresql_plr_tut01 http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgresql_plr_tut02 for a useful introduction to PL/R; and for rgdal, see: http://rgdal.sourceforge.net/ http://cran.r-project.org/web/packages/rgdal/rgdal.pdf http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgresql_plr_tut03 HTH, Brent Wood --- On Thu, 11/18/10, David Potts <[email protected]> wrote: From: David Potts <[email protected]> Subject: [postgis-users] Postgis & R language To: "PostGIS Users Discussion" <[email protected]> Date: Thursday, November 18, 2010, 12:46 AM Hi List Has anybody ever tried to read the value of geometry column from a table into a R-language application using the plr handler, is this a support option?
