objects assignment to something else

[CdeMills]

Hello,

say x is a [5, 5] dataframe while a is a [5, 5] double matrix. The following
assignment fails:
a(:, :) = x

with the message:
error: operator =: no conversion for assignment of `class' to indexed
`matrix'
error: assignment failed, or no method for `matrix = class'

This message originates from base/ov-base.cc, but I didn't manage to trace
the full call chain, it probably starts from the internal subasgn(). Is
there a way, in this kind of operation, to either overload the copy
assignment operator, either call some specific object method in such a way
that it returns a copy of itself in the format of the LHS of the assignment
? 

Regards

Pascal
