 I have seen that there exists a software called RLink but it is not readil=
y available.  Is the way to go to use the R functionaly in C/C++  and t=
hen use MathLink to call the C/C++ functions?

Very interesting. I just downloading and installed RAndFriends from
rcom.univie.ac.at, which installs R, rcom, rscproxy, statconnDCOM, and
RExcel (I canceled the installation when I got to RExcel).

I order to run your code, I had to modify it as follows:

myR = CreateCOMObject["StatConnectorSrv.StatConnector"]

You example illustrates a number of methods, such as SetSymbol,
Evaluate, etc. I was able to infer

myR@Close[]

(and then use ReleaseCOMObject[myR]).

Do know where I might find the full set of methods?
