[Rd] Bridging R to OpenOffice

Still didn't get the point, or missed the topic ?
It's OpenOffice.org and R not Excel and R, two totally different 
products at least from a philosophical standpoint. Not everybody is 
willing to pay license fee for Excel to be able to use R via a GUI.
That's how the idea was born to integrate or bridge R with 
OpenOffice.org Calc
Access statistical data analysis functionality computed by the almighty 
R engine from menues in Calc, and getting the results back in Calc (more 
for users than for developers). A plugin could do the job.
There is no point in saying "there is something in Excel" like there is 
none in saying "Why not using "S" ?
You may want to follow the link, offered by Leonard, to the "Google 
Summer of Code"-project which is menthored by Sun Microsystems 
(Star/OpenOffice developers), to get a clearer picture about it.

best regards
