Nothing
Several tools for handling blockmatrix diagonals and similar constructs are implemented. Blockdiagonal matrices can be extracted or removed using two small functions implemented here. In addition, nonsquare matrices are supported. Block diagonal matrices occur when two dimensions of a data set are combined along one edge of a matrix. For example, tradeflow data in the 'decompr' and 'gvc' packages have each countryindustry combination occur along both edges of the matrix.
