[R] COM objects with early bindings in R

[It is best to ask these questions on the omega-help at omegahat.org
mailing list or directly to me as the maintainer of the code.]

There are new versions of the RDCOM packages. They are not
officially released because I haven't had time yet.
But they are available from

 http://www.omegahat.org/Prerelease/


The function generateInterface() is now used to create a better
collection of code than the old createCOMSClass() function.

Then something along the following lines (depending on your taste)
will do create the interface code.  If you want events, set events =
TRUE.  You can output the result into a directory and many files or
a single file or text connection depending on what you want (i.e.
package or direct use).


library(SWinTypeLibs)

library(RDCOMClient)
library(RDCOMServer)

library(RDCOMEvents)

	
e = COMCreate("Excel.Application")
options(error=recover)	

lib = LoadTypeLib(e)	

# Generate the code to interface to ALL the classes.
tmp = generateInterface(lib, "Workbooks", events = FALSE)

out = writeCode(tmp, "ExcelCode.S")


I'd love some feedback.
