パッケージ 'Matrix' の情報 記述: Package: Matrix Version: 0.999375-31 Date: 2009-10-06 Priority: recommended Title: Sparse and Dense Matrix Classes and Methods Author: Douglas Bates <bates@stat.wisc.edu> and Martin Maechler <maechler@stat.math.ethz.ch> Maintainer: Doug and Martin <Matrix-authors@R-project.org> Description: Classes and methods for dense and sparse matrices and operations on them using Lapack and SuiteSparse. Depends: R (>= 2.9.0), stats, methods, utils, lattice Imports: graphics, lattice, grid, stats Enhances: graph, SparseM SystemRequirements: GNU make LazyLoad: yes LazyData: no LazyDataNote: no longer available, since we use data/*.R *and* our classes License: GPL (>= 2) LicenseDetails: The Matrix package includes libraries AMD, CHOLMOD, COLAMD, CSparse and SPQR from the SuiteSparse collection of Tim Davis. All sections of that code are covered by the GPL or LGPL licenses. See the directory doc/UFsparse for details.
