I don't want to delay the release, but the interface (signature) of the
new function msplitby() strikes me as odd. The example in the built-in
reference is a perfect (sic!) example for this oddity - the matrix X
should be split into two chunks (AFAICS), but instead of being able to
write...
msplitby(X, {1,1,3}) # unsupported syntax currently
the example goes like...
msplitby(X ~ {1,1,3}', 4)
which even to me as a veteran hansl coder looks quite complicated. I
don't really see the advantage of the latter formulation.
I think you're right. If the split-index column is treated as special
(specifically, not wanted in the output) it would be cleaner to make
the second argument a vector in its own right rather than a column
number.
Since this function is not present in any release I guess we could
change the signature now.
