R help - Nov 2004 - using R in .NET apps

looking for some thoughts on incorporating R functionality to create
histograms of data stored in an informix db.  im gonna write the app in .Net
and will use a managed provider to access the data. what R libs might I have
to package in the assemblies? (sorry my Q is general as Ive only just looked
at wanting this yet)

Thanks. Amer.

Could you translate the question into English?  My guess is that you are
writing in a lower-cased version of some Microsoft internal language, but
you don't even mention that this is for Windows (if it is).

I am writing a windows XP app which utilizes the .NET framework. my language
is VB.NET. the Visual basic (VB) compiler will translate VB source code into
microsoft intermediate language (MSIL), thus producing native code on XP.

if I have a multi-tier app with a lower layer datastore (IBM Informix using
ODBC) and a middle tier (for logic and computation), I would like to
incorporate R functionality at this stage and send output to the front end
(display charts, etc.).  

Currently, the .NET IDE incorporates the "Crystal Report" engine for
such
needs.  I would like to use R in a similar manner. Perhaps I could expose it
as a windows service (using DCOM?), thus allowing me to programmaticaly
access its abilities within the .NET framework.
