R devel - Jul 2014 - request of information about creating DLL from R to be used in other languages/programs

Hello

 

My question is the following. I have tried to find a similar subject in
archives but not found (perhaps bad search!) and I tried R-help and I was
advised that R-devel would perhaps better for my question

 

So I wonder if it is possible to create a dll from a R code to use it in
another language/program.

Indeed, one of my colleague wrote a R code combining some R functions to
create a method of calculation.

I would want to use this method in a program coded in Delphi.

 

Is there possibilities to create a DLL from R code to be called in the
Delphi program ?

It would allow us to avoid rewriting code and searching correspondence
between R functions and Delphi program (or other types of tools as TPMath).

Is it possible to call a dll form R whereas R is not installed on the
computer?

 

I hope to be clear in my demand an I hope you will be able to give me some
indications or where to find it.

 

Best regards

 

Ludovic Brossard

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:
