BlockedInfinitySparseMatrix-class function

Blocked Infinity Sparse Matrix

Blocked Infinity Sparse Matrices are similar to Infinity Sparse Matrices, but they also keep track of the groups of units via an additional slot, groups class

Slots

• groups: factor vector containing groups, with unit names as labels, when possible
• colnames: vector containing names for all control units. This will either be a character vector or NULL if units have no names
• rownames: vector containing names for all treated units. This will either be a character vector or NULL if units have no names
• cols: vector of integers corresponding to control units
• rows: vector of integers corresponding to treated units
• dimension: integer vector containing the number of treated and control units, in that order
• call: function call used to create the InfinitySparseMatrix
