You can, using R(DCOM) which is installed by the Windows installer. There 
is a separate list to discuss this, but it is mainly focused on Excel 


When you select the full install of R(D)COM, you also get an MFC/C++ sample.
C#/.NET works, I use it heavily, and you can generate nice interfaces for R 
with it. You must reference StatConnectorClntLib, StatconnectorCommonLib,
StatConnectorSRVLib, and you get an implicit reference to
AxStatConnectorClntLib. No explicitely generated DLL is required with 
Visual Studio, but don't expect this to work easily when you fear DLL 

There is a major problem with Data Excecution Prevention and installation of 
C# procedure calling R(D)COM with Vista which I only could get around 
by disabling DEP.
