[postgis-users] Postgis & R language

[pcreso at pcreso.com]

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:

for a useful introduction to PL/R; and for rgdal, see:

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?

Thanks in advance.
