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 | <browse to .pas file> | 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.
