Re: R Mathlib

Hello,

 

May I ask, since R is also an open-source application, in addition to include R’s components, can we also reference R’s internal algorithms when coding for octave and octave-forge ?  Thanks.

 

Best regards,

 

Hong Yu

While working on binopdf I noticed that there is a useful
collection of special functions in:

============================================

Would it make sense to consider adopting this whole set into Octave
in a way that would make updates fairly automatic?   I know for sure that
at least the probability and statistics functions in this library are very good
and actively maintained by the R group.

I do not think that there are any copyright issues, but there could be compatibility
and other  items to consider.  The R view of compatibility with Matlab is quite different
from the Octave's.

If this were done, an accurate and fast binopdf would be "automatic."  Roughly,
binopdf would just call the C dbinom function.

Comments?
