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
The packages can be downloaded collectively from
or individually from
