Matrix (version 0.99-3)

dgBCMatrix-class: Class "dgBCMatrix" Real Sparse Blocked Column Compressed Matrix

Description

The dgCMatrix class is a class of sparse blocked matrices in the compressed, sparse, column-oriented format. In this implementation the non-zero elements in the columns are sorted into increasing row order.

Arguments

Objects from the Class

Objects can be created by calls of the form new("dgBCMatrix", ...).

Objects in this class have a structure similar to those in the dgCMatrix class except that each nonzero element is itself a dense matrix with a given number of rows and columns. These objects are used in the representation of linear mixed-effects model structures in the lme4 package.
