Real 2.0 --- 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 [1] 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. Licence --- This software can be distributed under the MIT licence (see prolog/real.pl). INSTALL --- To install stable versions: SWI-Prolog ?- pack_intall( real ). Yap install Yap itself with configure --with-R See doc/guide.pdf for further details on stable versions. Git access --- To get the latest git version goto git clone https://github.com/nicos-angelopoulos/real To install developmental versions do: SWI-Prolog (a) 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 configure --with-R Test --- SWI ?- [pack('pack/real/examples/for_real')]. ?- for_real. 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.
