R as COM client (rather than server)
There is also the Omegahat collection of packages for DCOM which supports R as a client, user-definable server objects and event handlers. Together, RDCOMClient and RDCOMServer (and the SWinRegistry and SWinTypeLibs packages) provide a general way to handle arbitrary data types in R and COM. There is a description of how this differs from the S-Plus approach and Thomas' rdcom package. See http://www.omegahat.org/RDCOMClient

It can be done. But it is still in development and therefore not on CRAN. There is a library rcom which does exactly what you are asking for. http://sunsite.univie.ac.at/rcom/ always has the latest version of the R COM package, currently including the package for R as a client also. There is a special mailing list for questions related to R and (D)COM you can subscribe to it at http://mailman.csd.univie.ac.at/mailman/listinfo/rcom-l DED (David George Edwards) wrote:
Hello all
Can R be used as a COM client (rather than as a COM server)? The following
(Splus) code shows the sort of thing I'd like to do:
pMIM <- create.ole.object("mim31.Server")
NoOutputLines <- call.ole.method(pMIM, "SendCmdLine", "show w")
for (i in 1:NoOutputLines) show(call.ole.method(pMIM,
"GetOutputLine"))
release.ole.object(pMIM)
I've tried to look at the RDCOM documentation but could not figure out
whether this can be done.
