1    2006-09-18  Douglas Bates  <bates@stat.wisc.edu>
2    
3            * R/[CT]sparse.R (crossprod and tcrossprod): Handle the cases for x
4            symmetric and y missing in R code using %*% (cholmod_aat doesn't
5            accept a symmetric matrix).
6            * tests/group-methods.R: Uncomment test of crossprod applied to
7            lsCMatrix objects.
8    
9    2006-09-18  Martin Maechler  <maechler@stat.math.ethz.ch>
10    
11            * R/AllClass.R (symmetricMatrix): add validity method (available
12            in C for a long time). Many "n..Matrix": drop (wrong) validity arg.
13    
14            * src/lgCMatrix.c (lgCMatrix_validate): check 'x' slot (!)
15    
16            * tests/indexing.Rout.save:
17            * tests/indexing.R: additions, mainly for 'lsparse'
18    
19            * R/diagMatrix.R (Diagonal) & coercion to lgTMatrix: fixes for NA
20            case.
21    
22            * R/Auxiliaries.R (nz.NA): new utility now used in nnzero()
23    
24    2006-09-16  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * R/sparseMatrix.R (prSpMatrix): print logical NAs "visibly"
27                    as 'N' (1-letter - Ok?)
28    
29            * tests/group-methods.R: add test for logical + NAs
30    
31            * R/dMatrix.R ("Compare"): fix to work with NA's
32    
33            * R/AllClass.R: "Cholesky" etc now inherit from MatrixFactorization.
34    
35            * src/lgCMatrix.c (ncsc_to_matrix): renamed from lcsc_to_matrix()
36                    which is implemented.
37    
38    2006-09-15  Martin Maechler  <maechler@stat.math.ethz.ch>
39    
40            * src/chm_common.c: coerce logical <-> double instead of
41            typecasting;  needed for "l" matrix handling in cholmod.
42    
43            * tests/other-pkgs.R (graph): small extension in "graph" checks.
44    
45            * R/sparseMatrix.R (graphNEL -> Tsparse): method for weight case.
46            (Tsp2grNEL): other fixes needed
47    
48    2006-09-11  Martin Maechler  <maechler@stat.math.ethz.ch>
49    
50            * R/AllClass.R ("nMatrix"): and subclasses for "nonzero pattern"
51                    Matrices, since "lMatrix", also "lsparseM" can have NA
52            * R/ndenseMatrix.R, etc: new source files
53            * man/nsparseMatrix-classes.Rd, etc: new help files
54            * tests/: adaptions
55            * src/chm_common.c (chm_dense_to_SEXP): and others:
56                    new 'Rkind' argument: "l*" and "d*" both use CHOLMOD_REAL
57            * src/Csparse.c, etc: dito
58    
59    2006-09-11  Douglas Bates  <bates@R-project.org>
60    
61            * src/Mutils.[ch],init.c inst/include/*.h: Move the
62            alloc_d**Matrix functions to the lme4 package.
63    
64    2006-09-09  Douglas Bates  <bates@R-project.org>
65    
66            * src/dsCMatrix.c (dsCMatrix_Cholesky): igoring LDL = FALSE now
67            fixed
68    
69    2006-09-09  Martin Maechler  <maechler@stat.math.ethz.ch>
70    
71            * R/lMatrix.R: new
72    
73            * R/sparseMatrix.R (Tsp2grNEL): do not yet use graph::foo()
74    
75            * R/dgeMatrix.R: do not define tcrossprod() methods for "matrix"
76            * man/tcrossprod.Rd: dito
77    
78    2006-09-08  Douglas Bates  <bates@stat.wisc.edu>
79    
80            * inst/include/Matrix_stubs.c,Matrix.h: Add declarations and stubs
81            for exported functions
82            * src/Makefile, src/CHOLMOD/Lib/Makefile, src/Metis,CAMD,CCOLAMD:
83            Remove partitioning algorithms for sparse matrix reordering.  The
84            copyright on the Metis code was problematic and the methods were
85            rarely used.
86            * src/triplet_to_col.[ch],MMHB.[ch]: Remove triplet_to_col.  Such
87            operations are now done entirely in CHOLMOD code.
88    
89    2006-09-06  Douglas Bates  <bates@R-project.org>
90    
91            * src/Mutils.h: Remove functions that are no longer used.
92    
93    2006-09-04  Douglas Bates  <bates@R-project.org>
94    
95            * src/dtCMatrix.c (dtCMatrix_validate): rename functions.
96            * src/DEPS.mkf: update
97    
98    2006-09-02  Martin Maechler  <maechler@stat.math.ethz.ch>
99    
100            * created branches/Matrix-for-R-2.3.x;  on trunk: do
101            * DESCRIPTION (Version): 0.9975-0
102            (Depends): R (>= 2.4.0)
103    
104    2006-09-01  Douglas Bates  <bates@R-project.org>
105    
106            * R/sparseMatrix.R: Added direct method to CsparseMatrix from graphNEL
107    
108  2006-09-01  Martin Maechler  <maechler@stat.math.ethz.ch>  2006-09-01  Martin Maechler  <maechler@stat.math.ethz.ch>
109    
110          * R/sparseMatrix.R: add coercion from "ANY" to "sparseMatrix"          * R/sparseMatrix.R: add coercion from "ANY" to "sparseMatrix"
