1    2007-02-05  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/SparseM-conv.R: more conversion, notably for triplet matrices.

7    
8            * DESCRIPTION (Version): 0.9975-10 to upload
9    
10            * tests/Class+Meth.R (tstMatrixClass): require coercions to
11            specific classes less unconditionally.
12    
13            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
14    
15            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
16    
17            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
18            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
19            R_to_CMatrix segfaults on one platform.
20            Eliminate most coercion method to *specific* classes, and replace
21            with virtual classes coercions.
22    
23    
24    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
25    
26            * src/init.c: export the CHM...._validate() placeholders, since
27            they *are* called.
28    
29            * tests/Class+Meth.R (classCanCoerce): and starting to test
30            all as(<from>, <to>)
31    
32    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>
33    
34            * R/Tsparse.R ([): more care when subsetting triangular Tsparse
35            * tests/indexing.R: tested now
36            * tests/indexing.Rout.save: updated
37    
38            * src/Csparse.c (Csparse_to_dense): use Rkind = -1 for PATTERN to
39            * src/chm_common.c (chm_dense_to_SEXP): return "ngeMatrix" when
40            appropriate.
41    
42            * NAMESPACE: export a trivial
43            * R/Matrix.R: drop() Matrix-method
44    
45            * R/AllClass.R: moved all prototypes to virtual super classes.
46    
47            * R/Rsparse.R: many more coercions to have less exceptions in
48            * tests/Class+Meth.R:
49    
50            * R/Ops.R (Compare): tweak for case with NA
51            * tests/simpl.R: hence another 'FIXME' eliminated
52    
53    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
54    
55            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
56            objects.
57    
58            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
59              and more of "!", "&", "|", all, any; coercions
60    
61            * R/Rsparse.R: many coercions (which enable quite a few other
62            methods), thanks to enhancements in
63            * src/dgCMatrix.c (R_to_CMatrix): new, and
64            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
65            symmetric & triangular and ..RMatrix objects.
66    
67            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
68            renamed file from src/dsTMatrix.c;
69            now dealing with symmetric and triangular Tsparse coercions, both
70            to dense and general.
71    
72    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
73    
74            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
75    
76            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
77            where sensible when the <numeric> is of length > 1.
78    
79    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
80    
81            * R/Matrix.R ([<-): for M[] <- value: fix length
82    
83    2007-01-25  Martin Maechler  <maechler@stat.math.ethz.ch>
84    
85            * R/Auxiliaries.R (n2l_Matrix): new, to be used in
86            * R/ndenseMatrix.R: new coercions n* -> l*
87    
88    2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
89    
90            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
91    
92            * R/Ops.R ("Logic"): and other "Ops", many updates
93    
94    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
95    
96            * src/Mutils.h (SET_DimNames): new utility
97    
98            * R/Auxiliaries.R (nnzero): improved and now exported via
99    
100            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
101    
102    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
103    
104            * R/diagMatrix.R (!): fix typo.
105    
106    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
107    
108            * R/Auxiliaries.R (as_Csparse): and quite a few others:
109                    allow to pass class definition --> speedup
110            * R/sparseMatrix.R: apply the above
111    
112            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
113    
114            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
115            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
116            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
117    
118            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
119    
120            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
121            and use it for "sparse*" as well, since it's faster than the
122            as_Csparse(.) way.
123    
124    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
125    
126            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.
127    
128    2007-01-12  Martin Maechler  <maechler@stat.math.ethz.ch>
129    
130            * R/Tsparse.R (.TM.repl.i.2col): new internal function to be used
131            as method for   M[ ij ] <- v
132            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
133    
134            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
135            FALSE answer
136    
137            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
138            * tests/indexing.R: test it, and some of the above
139    
140    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>
141    
142            * R/Auxiliaries.R (is_duplicatedT): new utility
143    
144  2007-01-05  Douglas Bates  <bates@stat.wisc.edu>  2007-01-05  Douglas Bates  <bates@stat.wisc.edu>
145    
146          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale
147    
148    2006-12-30  Martin Maechler  <maechler@stat.math.ethz.ch>
149    
150            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
151            base::as.matrix to (x, ...)
152    
153  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
154    
155          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
