1    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
4              and more of "!", "&", "|", all, any; coercions
5    
6            * R/Rsparse.R: many coercions (which enable quite a few other
7            methods), thanks to enhancements in
8            * src/dgCMatrix.c (R_to_CMatrix): new, and
9            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
10            symmetric & triangular and ..RMatrix objects.
11    
12            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
13            renamed file from src/dsTMatrix.c;
14            now dealing with symmetric and triangular Tsparse coercions, both
15            to dense and general.
16    
17    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
18    
19            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
20    
21            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
22            where sensible when the <numeric> is of length > 1.
23    
24    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * R/Matrix.R ([<-): for M[] <- value: fix length
27    
28    2007-01-25  Martin Maechler  <maechler@stat.math.ethz.ch>
29    
30            * R/Auxiliaries.R (n2l_Matrix): new, to be used in
31            * R/ndenseMatrix.R: new coercions n* -> l*
32    
33    2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
34    
35            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
36    
37            * R/Ops.R ("Logic"): and other "Ops", many updates
38    
39    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
40    
41            * src/Mutils.h (SET_DimNames): new utility
42    
43            * R/Auxiliaries.R (nnzero): improved and now exported via
44    
45            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
46    
47    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
48    
49            * R/diagMatrix.R (!): fix typo.
50    
51    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
52    
53            * R/Auxiliaries.R (as_Csparse): and quite a few others:
54                    allow to pass class definition --> speedup
55            * R/sparseMatrix.R: apply the above
56    
57            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
58    
59            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
60            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
61            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
62    
63            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
64    
65            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
66            and use it for "sparse*" as well, since it's faster than the
67            as_Csparse(.) way.
68    
69    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
70    
71            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.
72    
73    2007-01-12  Martin Maechler  <maechler@stat.math.ethz.ch>
74    
75            * R/Tsparse.R (.TM.repl.i.2col): new internal function to be used
76            as method for   M[ ij ] <- v
77            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
78    
79            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
80            FALSE answer
81    
82            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
83            * tests/indexing.R: test it, and some of the above
84    
85    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

96            base::as.matrix to (x, ...)
97    
98    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
99    
100            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
101            file; start using "Logic", hence
102    
103            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
104            * NAMESPACE: import and export "Logic"

192            to LL before converting to a sparse matrix. (The LDL form can be
193            converted to a sparse matrix but it is implicitly a unit
194            triangular matrix and a diagonal matrix overwritten on the diagonal.)
195    
196    2006-12-09  Douglas Bates  <bates@stat.wisc.edu>

206    
207          * R/diagMatrix.R (%*%): write a direct [diag o Csparse] method          * R/diagMatrix.R (%*%): write a direct [diag o Csparse] method
