382    
383            * R/AllClass.R (symmetricMatrix): add validity method (available

387    
388            * tests/indexing.Rout.save:

402    
403            * R/dMatrix.R ("Compare"): fix to work with NA's
404    
405            * R/AllClass.R: "Cholesky" etc now inherit from MatrixFactorization.
406    
407            * src/lgCMatrix.c (ncsc_to_matrix): renamed from lcsc_to_matrix()
408                    which is implemented.

410    2006-09-15  Martin Maechler  <maechler@stat.math.ethz.ch>
411    
412            * src/chm_common.c: coerce logical <-> double instead of
413            typecasting;  needed for "l" matrix handling in cholmod.
414    
415            * tests/other-pkgs.R (graph): small extension in "graph" checks.
416    
417            * R/sparseMatrix.R (graphNEL -> Tsparse): method for weight case.

423                    Matrices, since "lMatrix", also "lsparseM" can have NA
424            * R/ndenseMatrix.R, etc: new source files
425            * man/nsparseMatrix-classes.Rd, etc: new help files
426            * tests/: adaptions
427            * src/chm_common.c (chm_dense_to_SEXP): and others:
428                    new 'Rkind' argument: "l*" and "d*" both use CHOLMOD_REAL

453            for exported functions
454            * src/Makefile, src/CHOLMOD/Lib/Makefile, src/Metis,CAMD,CCOLAMD:
455            Remove partitioning algorithms for sparse matrix reordering.  The
456            copyright on the Metis code was problematic and the methods were
457            rarely used.
458            * src/triplet_to_col.[ch],MMHB.[ch]: Remove triplet_to_col.  Such
459            operations are now done entirely in CHOLMOD code.

474            (Depends): R (>= 2.4.0)
475    
476    2006-09-01  Douglas Bates  <bates@R-project.org>

498    
499    2006-08-30  Martin Maechler  <maechler@stat.math.ethz.ch>
500    
501            * R/dgCMatrix.R: aargh: "Arith(<dgC>, numeric)" was wrong because
502            of a 0-index which was used as 1-index (..hmm)
503    
504            * R/sparseMatrix.R (prSpMatrix): fix printing an all-0 sparse Matrix
505
