Dmitriy Lyubimov commented on MAHOUT-1583:
------------------------------------------
Hm. Because. I would say, drm and data frames are two different
technologies,and "data frames have or do not have cbind" and "drm have or
do not have cbind" at this point are conditionally independent random
variables.

> Another R-like operator, cbind (stitching two matrices together). Seems to
> come up now and then.
> Just like with elementwise operations, and, perhaps some other, it will have
> two physical implementation paths, one is zip for identically distributed
> operators, and another one is full join in case they are not.
