A brief look at the internet shows that there are many more or less developed computer algebra packages freely available. Therefore, I wondered if it would be an idea to try to 'integrate' one of these packages in R, which I guess can be done in more or less elegant ways... I do not know any of the computer algebra people around the World, but perhaps some other people from the R-community do and would be able to/interested in establishing such a connection...

It sounds like developing an R package to act as a wrapper would be the 
best approach.  I didn't see documentation for their API (the exports of 
their DLL), but I didn't spend long looking.
