Re: [R] R (2.2.0), R-DCOM and Delphi
Dear Dieter, First, thank you for your work! Below the error message I got when trying to compile your RDCom.dpr [Warning] STATCONNECTORCLNTLib_TLB.pas(319): Unsafe type 'EventDispIDs: Pointer' [Warning] STATCONNECTORCLNTLib_TLB.pas(320): Unsafe type 'LicenseKey: Pointer' [Warning] STATCONNECTORCLNTLib_TLB.pas(324): Unsafe code '@ operator' [Warning] STATCONNECTORCLNTLib_TLB.pas(367): Unsafe type 'EventDispIDs: Pointer' [Warning] STATCONNECTORCLNTLib_TLB.pas(368): Unsafe type 'LicenseKey: Pointer' [Warning] STATCONNECTORCLNTLib_TLB.pas(372): Unsafe code '@ operator' [Warning] STATCONNECTORCLNTLib_TLB.pas(374): Unsafe code '@ operator' [Warning] STATCONNECTORSRVLib_TLB.pas(376): Unsafe type 'LicenseKey: Pointer' [Warning] STATCONNECTORSRVLib_TLB.pas(379): Unsafe code '@ operator' [Warning] RCom.pas(93): Unsafe code 'String index to var param' [Error] RCom.pas(119): Undeclared identifier: 'VarType' [Error] RCom.pas(124): Undeclared identifier: 'VarArrayDimCount' [Error] RCom.pas(127): Undeclared identifier: 'VarArrayHighBound' [Error] RCom.pas(140): Undeclared identifier: 'VarType' [Error] RCom.pas(145): Undeclared identifier: 'VarArrayDimCount' [Error] RCom.pas(148): Undeclared identifier: 'VarArrayHighBound' [Error] RCom.pas(161): Undeclared identifier: 'VarType' [Error] RCom.pas(166): Undeclared identifier: 'VarArrayDimCount' [Error] RCom.pas(169): Undeclared identifier: 'VarArrayHighBound' [Error] RCom.pas(181): Undeclared identifier: 'VarArrayCreate' [Error] RCom.pas(196): Undeclared identifier: 'VarArrayCreate' [Error] RCom.pas(211): Undeclared identifier: 'VarArrayCreate' [Error] RCom.pas(226): Undeclared identifier: 'VarArrayCreate' [Error] RCom.pas(253): Undeclared identifier: 'VarType' [Error] RCom.pas(258): Undeclared identifier: 'VarArrayDimCount' [Error] RCom.pas(261): Undeclared identifier: 'VarArrayHighBound' [Fatal Error] RDComMain.pas(14): Could not compile used unit 'RCom.pas' I'm using Delphi 7 under WinXP pro/SP2.

finding to the archive.
Here's what worked for me:
(1) Install the new (D)COM server (the old one gives the error Method '~'
of object '~' failed with R 2.2.0):
For anybody who wants to try the R(D)COM server alone, I recommend
http://sunsite.univie.ac.at/rcom/download/RSrv200beta.exe
It is reasonably stable and will work with R 2.2.0.
(2) In C:\Program Files\R\(D)COM Server\samples\Simple run the simple.exe to
verify the server is working.
(3) Download and unzip: http://www.menne-biomed.de/download/RDComDelphi.zip
Like Jose Claudio Faria described, a number of warnings and errors will be
seen in Delphi 7 in compiling the unmodified RDCom.dpr project.
To fix the compilation errors, add the Variants unit to the uses:
uses
Windows, Messages, SysUtils,Classes, Dialogs,
STATCONNECTORSRVLib_TLB,Forms, Variants;
I don't remember why Borland made this change.
You can make the Warnings go away by selecting Project | Options | Compiler
Messages and unchecking the boxes for
- Unsafe type
- Unsafe code
These warning were introduced with Borland made changes to support .NET.
The code should be quite fine for Win32.
Note: The Delphi source code could be modified to use {$IFDEF} directives
to take care of the differences by compiler version. See the Compiler
Versions section of this page:
http://www.efg2.com/Lab/Library/Delphi/Miscellany/index.html.
Unfortunately, Borland has not been very helpful in promoting the use of a
common Versions.INC file or any other mechanism to take care of such
compiler version problems in a uniform way. The file Versions.INC must be
updated with every new release by Borland.
(4) Run the RDCom.exe program. Select the Run and Plot buttons and see a
wonderful demo of Delphi and R working together. (Now I can get busy and
use this in other Delphi applications with R as a backend.)
Thanks for the work on R-DCOM and this great example!

[R] R (2.2.0), R-DCOM and Delphi
In response to a few private e-mails, here a summary of using Delphi, R-DCOM and R 2.2.0 1) As Earl Glynn noted ( http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50705.html ), there were a few paths specific to my installation in http://www.menne-biomed.de/download/RDComDelphi.zip leading to path errors on compilation. Hopefully, this has been corrected in the new zip file. 2) Always check if the test samples (e.g. simple.exe) coming with R(D)COM work before trying with Delphi. Parameters passing fails with R 2.2.0 and old R(D)COM, but graphs still work. For R 2.2.0, please read http://mailman.csd.univie.ac.at/pipermail/rcom-l/2005-October/000764.html and download the new versions. After installing the new versions, my Delphi talks again with R.
