[R] R API call from delphi
Hello, Has anyone tried to call R API from Delphi under windows ? How was it done if it was ? Or has anyone any idea about how it could be done ?

Re: [R] R API call from delphi
On approach is to create a native/foreign interface to R by linking R as a library (libR.a and R.dll) file and calling the C routines in the library to i) initialize the R interpreter ii) call an R function We have done this with many languages and the procedure is well understood at this point, but requires some C-level programming and converting between the standard data types of both systems. Another approach is to use R via DCOM. There are two different approaches to this. One has the R interpreter as the DCOM server and the client (the Delphi application here) would send R commands to that server. The other approach has regular DCOM servers that are implemented via R functions. (The ability to send R commands is a simple case of this.) It is up to you to define the servers via a few extra lines of R code. I would suggest you pursue the DCOM route unless you are keen to do the necessary work to embed the R library in Delphi and deal with some technical details about calling conventions of C routines.
