See http://www.joeconway.com/plr/ for release notes
Notes:
- R headers are required. Download and install R prior to building
PL/R.
- R must have been built with the --enable-R-shlib option when it was
configured, in order for the libR shared object library to be available.
- R_HOME must be defined in the environment of the user under which
PostgreSQL is started, before the postmaster is started. Otherwise
PL/R will refuse to load.
Installation:
See http://www.joeconway.com/plr/doc/plr-install.html
for the most up-to-date instructions.
Place these files in a directory called 'plr' under 'contrib' in the
PostgreSQL source tree. E.g. place the tarred source file in
'/path/to/pg_source/contrib' and run:
tar -xzf plr-x.y.z-alpha.tar.gz
Then run:
cd /path/to/pg_source/contrib/plr
make
make install
make installcheck
This is usually best done logged in as the PostgreSQL superuser
(defaults to postgres), except root privileges may be needed for
"make install".
You can use plr.sql to create the functions in your database of choice, e.g.
psql mydatabase < plr.sql
Documentation:
See the following files:
doc/plr.sgml - PL/R documentation source
doc/*.html - Preprocessed html version of the documentation
