I have finally got around to putting 4 packages
on the Omegahat web site for use on Microsoft Windows.
The packages are:

RDCOMClient - interactive, dynamic access to arbitrary (D)COM objects
 from within R that allows one to create COM objects
 from R and call their methods and access their properties without 
 the need to compile any code specific to the COM object.

RDCOMServer - facility for defining COM classes entirely within
 R using functions and values as methods and properties. 
 This is a more general model than the one in S-Plus and the
 Thomas Baier's RDCOM facility.  It allows clients to see 
 S-COM objects as regular COM objects without needing to know
 the S language or create S commands.
 It also allows arbitrary S objects to be used as arguments in calls
 from the RDCOMClient package, and can be used to handle events from
 COM objects such as ActiveX controls, Excel.

SWinRegistry - facilities for accessing the Windows registry and its contents.
  One can read and write values, create keys, and navigate the hierarchy.

SWinTypeLibs - R interface to read Windows type libraries describing COM objects,
  C routines, etc.  This allows us to "compile" methods for accessing COM 
  objects from R more efficiently and with better local error-handling.

The packages are reasonably stable but could benefit from people using
them further.

The packages can be downloaded collectively from 


or individually from

  http://www.omegahat.org/<package name>.
