Most of this is possible, but not easy. See chapter 8 of the "Writing R Extensions" manual. You are essentially writing a new "front-end" to R, and it will require R to be installed for it to work. Many years ago I wrote instructions for using Delphi to create a DLL for R to use, which is another approach you could try. I've no idea how obsolete those instructions are nowadays, but they might give you some starting points: http://www.stats.uwo.ca/faculty/murdoch/software/compilingDLLs/pascal.html Duncan Murdoch > > > Best regards > > > > Ludovic Brossard > > > > > > > > Ludovic BROSSARD > > UMR PEGASE (Physiologie, Environnement et Génétique pour l’Animal et les > Systèmes d’Elevage) > > INRA – Agrocampus Ouest > > Domaine de la Prise, 35590 Saint-Gilles, France > > Tél : 33 (0)2 23 48 70 57 .
