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.

I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7, browser is Firefox) Just starting Rpad by library(Rpad) Rpad() opens the browser and displays the .html files and the .Rpad files in my home directory, but these files do not have links and are not clickable.
