R have a native class of objects of class 'matrix':
they can only be squared
They are atomic vectors with 'dimension' attribute (2 coordinates)

Since R is an object-oriented language,
a user can specify as many new classes of data as she wants

Matrix package has many additional classes of  "matrices"
It's unreal to have gretl native interface to much
classes defined in packages (about 10^4 packages in cran only)

It's more realistic to coerce some "matrix"
to a native (i. e. defined in r-base) class of objects
and only then export them

One of the reasons to stick with gretl!

Hehe,
