|Pack real -- README.txt|
Real is a c-based interface for connecting R to Prolog. See the documentation at doc/html/real.html for more information. There is also a paper  and a user's guide in doc/guide.pdf.
Real works on current versions of SWI and YAP. As of version 1.1 there is support for using Real on SWI web-servers.
This software can be distributed under the MIT licence (see prolog/real.pl).
To install stable versions:
pack_intall( real ).
Yap install Yap itself with configure --with-R
See doc/guide.pdf for further details on stable versions.
To get the latest git version goto
To install developmental versions do:
Install last stable real with
pack_install( real ).
replace the pack/real directory with the clone from git repository and do
pack_rebuild( real ). % to force SWI to build from sources.
SWI-Prolog (b) clone real into pl-devel/packages/real add this to your build script export EXTRA_PKGS="real" build SWI from sources as per usual
Yap replace $YAP/packages/real with the development version you downloaded and rebuilt Yap with
Yap ?- [examples/for_real]. ?- for_real.
Thanks, Samer Abdallah, for web support improvements.
Jan Wielemaker, for reimplenting the C-interface of the prototype for v1.0, for dots in identifiers (without flags) and web-support.
