You may have already seen it, but there is also the scaddins module
where you can add new functions. This module was there originally to

I don't know if this module is actively used today (Niklas?). I
Niklas -- I'll focus on UNO components then. There will definitely be
dialogs and visual guides for people, but I've been focusing on functions
because I'd like to build something that can use any function in R, sort of
like a very basic scripting process that can send anything to R and get the

These are just my views, but hopefully they will be useful in some
way. :-)

Hi,
Sound good. I'll worry about getting it to work rather than making it
GPL-compatible.
A little off-topic now, but I wrote an article for the wiki on adding
functions to the Calc code:

Feel free to comment, add, etc.
Hi,
this is the answer for a similar question I once asked Niklas:
Find the function name in sc/source/core/src/compiler.src, the
corresponding OpCode value in sc/inc/opcode.hxx, and look in
ScInterpreter::Interpret (sc/source/core/tool/interpr4.cxx) which
method is called for the OpCode.
Thanks for the responses!
With regards to GPL / LGPL issues, I understand the macro code would be
under GPL, but is that okay from your end? I don't mind that license, but am
not sure how OO developers feel. :)
Regarding the bias in the macro (missing = 0) -- yes, this is a problem but
the goal
Hi Niklas,
could you please explain what this code does?
{
ScMatValType nType = GetDoubleOrStringFromMatrix( fVal, rString);
bIsString = (nType != SC_MATVAL_VALUE);
}
My thinking is:
- it gets content of current table cell
- IF content is a numerical value, fVal is set
- IF content is string,

Nice to see the work started. There is still a lot to do, but at least
the work has started and it is possible to connect Calc to R.
