Good point about the graphics - I haven't thought of that. I will have to
look into that a bit tonight.

Just wondering -- for the OOo site, why can't the package be GPL? Unless
people are downloading it with OOo, my (limited!) understanding is that it
could be a different license. That being said, if it needs to be under LGPL,
then I'll have to build my own R/Calc connection.

Thanks,
Wojciech

Now let's not mix up things with regards to "external". From an
implementation point of view, this should be a UNO component, not part
of the Calc module.

But still I would strongly prefer a component that's available from the
OOo site, under LGPL. Even if users have to install R separately, having
the component on the OOo website would greatly improve its visibility to
OOo users.

If you want to use the connection via Rserve as a prototype to get the
rest of the component implemented, make sure that the dependencies on
Rserve remain limited, so it's possible to replace it later.

Regarding the use of add-in functions, one of the original ideas was to
also allow graph images as results. Cell formulas can't handle that.
