This function constructs a new ColumnLinkedMatrix
or
RowLinkedMatrix
object from a list of matrix-like objects.
ColumnLinkedMatrix(...)RowLinkedMatrix(...)
A sequence of matrix-like objects of the same row-dimension (for
ColumnLinkedMatrix
) or column-dimension (for
RowLinkedMatrix
).
Either a ColumnLinkedMatrix
or a RowLinkedMatrix
object.
A matrix-like object is one that has two dimensions and implements at least
dim
and [
. Each object needs to have the same number of rows
(for ColumnLinkedMatrix
) or columns (for RowLinkedMatrix
) to
be linked together. If no matrix-like objects are given, a single 1x1 node
of type matrix
filled with NA
is returned.
LinkedMatrix
objects can be nested as long as they are conformable.
LinkedMatrix
to create an empty, prespecified
LinkedMatrix
object.

# To specify the matrix-like objects as a list, use the `do.call` function
