DDE is a VERY old technology. I would avoid it if possible.

Hi,
Thanbks,
-I will try this.
- Do you know of "tcltk2" package
Which might have a "tk2dde" utility
I could not find examples of usage ...

An: R (D)COM and RExcel server related issues
Betreff: Re: [Rcom-l] WG: Usage of R and excel at the com layer
When it comes to Excel,
I think I should answer ;-)
There are 2 technologies supporting R in Excel:
(D)COM server and R pakage rcom.
From the user's point of view the main difference is that the (D)COM
server remains totally invisible whereas when using rcom the user
also has full access to the RGui.
I you develop things in R, it is probably better to use rcom.
The easiset way to install this is installing the packages rcom and
RExcelInst from CRAN.
Start by trying this.

=> The (D)COM Server appeared in the windows startmenue .
And then tried
Library(rcom) and received:
Es gibt kein Paket rcom
excel <- comGetObject("Excel.Application")
From R console. ( version R 2.7.2)
An excel spreadsheet was already opened.
Unfortenately I received an error:
"Konnte Funtion comGetObject nicht finden".
Do you have any ideas how to cope with that situation ?
Is there an essential "step" missing between installation of DCOM
and the command from R console ?
PS: I speak german as well.
