Re: [R] how to call R in delphi?

I downloaded this file and tried to compile the RDCom project using Delphi 5 and Delphi 7 but I get this message from both compilers: [Fatal Error] STATCONNECTORCLNTLib_TLB.pas(406): Could not create output file 'c:\program files\borland\delphi7\Twain\d5\dcu\STATCONNECTORCLNTLib_TLB.dcu' The "\db\dcu" in the path in this error message was a bit curious so I looked at Project | Options | Directories/Conditionals Unit output directory: $(DELPHI)\Twain\d5\dcu Search path: $(DELPHI)\Compon;C:\D2Pr\CascCont\COMPON;$(DELPHI)\Source\Toolsapi On my "vanilla" Delphi 5 and Delphi 7 installations all of the directories for the Unit output directory and Search path are invalid for the RDCom.dpr project. If I delete the Unit output directory, I then get 17 compilation errors, all like this: [Error] RCom.pas(115): Undeclared identifier: 'VarType' [Error] RCom.pas(141): Undeclared identifier: 'VarArrayDimCount' [Error] RCom.pas(123): Undeclared identifier: 'VarArrayHighBound' . . . All of the above seems to happen whether or not I install STATCONNECTORCLNTLib_TLB.pas and STATCONNECTORSRVLib_TLP.pas as components (i.e., Component | Install Component | | Open | OK | Compile). Am I supposed to do this at some point? Can you give me any clues how to make this work?

I went to http://cran.r-project.org/contrib/extra/dcom I read this documentation: http://cran.r-project.org/contrib/extra/dcom/RSrv135.html I downloaded and installed the R(COM) server (and rebooted) http://cran.r-project.org/contrib/extra/dcom/RSrv135.exe So, how I can I call "R" from Delphi using R(COM)? Something seems to be missing. Duncan Murdoch's suggestion about direct calls to R.dll looks interesting, but a complete working example would be nice. Thanks for any help with this. efg Earl F.

You can also use SOAP to communicate with R via RSOAP (http://rsoap.sf.net).

Re: [R] how to call R in delphi?
To call R from Delphi, you may try http://www.menne-biomed.de/download/RDComDelphi.zip. Example program showing use of R from Delphi. Connecting to R via COM using Neuwirth's StatConnectorSrvLib Uses RCom.pas, which is a simple Delphi wrapper for passing commands, integer and double arrays.

Thsnks. Tom referred you to a post about the COM interface. You can also do some of what you want with direct calls to R.dll. See the "R API: entry points for C code" section of the Writing R Extensions manual. If you're unfamiliar with calling C entries from Delphi, my web page <http://www.stats.uwo.ca/faculty/murdoch/software/compilingDLLs/> might help, though it is aimed at writing DLLs, rather than using R.dll. But that's another option: let R be in charge, and just add some functions in a DLL written in Delphi.

Try searching this list for delphi. This was the first post I found.
