The RDCOMEvents Package (version 0.3-1)
This package provides a mechanism for connecting
one or more R functions to a DCOM event source,
such as Excel, Word, and many more applications.
This allows R users to programmatically respond
to activities and specified events in other applications
using pure R code.
This package can be used along with the RDCOMClient package which provides
user-level access from S to other COM servers.
The ability to export S objects as COM values is important
for general bi-directional connectivity with other COM clients.
- We can display data in a new plot when an Excel
user switches between worksheets.
- When the Excel user selects one or more rows in the sheet,
color the corresponding points in an R plot.
- responding to updates and changes to data
stored in an Abstract Data Object (ADO) component.
- We can also use the RDCOMClient
package to create new controls in another application
such as buttons in a toolbar, a slider, etc. and catch the
action events on these components in R to customize
what should happen.
provides facilities for defining COM classes
implemented with R functions.
And the supporting packages

The facilities provided in this suite of packages are more
general than those provided
via the RCOM package
by Thomas Baier.
The model is more general and allows a more complete
set of computations on different data types and also
hides the R language from the client software connecting
The generality may make the interface appear more
complicated and slightly more indirect.
We believe that it is necessary and relatively simple
for developing non-trivial applications involving DCOM components
You can get binaries for these and install them simply by
unzipping them from within in the
This package was split out of the RDCOMServer package.
Some of the documentation remains there for the moment.
