A representation of a numeric matrix with row weights, represented
on either linear (`linwmatrix`

) or logarithmic (`logwmatrix`

)
scale.

An object of class `linwmatrix`

/`logwmatrix`

and `wmatrix`

,
which is a `matrix`

but also has an attribute `w`

containing
row weights on the linear or the natural-log-transformed scale.

Note that `wmatrix`

itself is an "abstract" class: you cannot
instantiate it.

Note that at this time, `wmatrix`

is designed as, first and
foremost, as class for storing compressed data matrices, so most
methods that operate on matrices may not handle the weights
correctly and may even cause them to be lost.
