Matrix (version 1.2-7.1)

dgRMatrix-class: Sparse Compressed, Row-oriented Numeric Matrices

Description

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

Note: The column-oriented sparse classes, e.g., dgCMatrix, are preferred and better supported in the Matrix package.
