[RDF] ROOT::VecOps::Combinations

Hi Everyone,

I was working the the vecOps::combinations function
https://root.cern/doc/master/RVec_8hxx_source.html#l00797
and was wondering why the order is the way it is. When using this with the VecOps::Map function, the loop is over the pair index (2) instead of the sets of pairs.

Perhaps I am using things incorrectly? Is there a way to transpose things?
EDIT: and I was…

I think I was just using it wrong…
