1    2007-02-12  Douglas Bates  <bates@stat.wisc.edu>
2    
3            * R/CHMfactor.R: Add image method (coercion to sparseMatrix).
4    
5    2007-02-05  Martin Maechler  <maechler@stat.math.ethz.ch>
6    
7            * DESCRIPTION (Date, Version): 0.9975-10 with new date.
8    
9            * R/Ops.R (Arith): make sure Csparse o Csparse also works for e.g. ntCMatrix
10            * tests/simple.R: test the above and some of these coercions:
11    
12            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
13                    be careful to avoid infinite recursion, using new coercions in
14            * R/ngCMatrix.R and nsC... and ntC...
15            * R/lsparseMatrix.R: ditto
16    
17            * R/SparseM-conv.R: more conversion, notably for triplet matrices.
18    
19            * src/dgCMatrix.c (R_to_C_Matrix): port Doug's fix and
20            * R/Rsparse.R: reactivate .Call()s
21    
22            * tests/Class+Meth.R: a bit more on actual classes
23    
24    2007-02-04  Douglas Bates  <bates@stat.wisc.edu>
25    
26            * src/dgCMatrix.c (compressed_to_TMatrix): fix memory bug using strdup()
27    
28    2007-02-03  Martin Maechler  <maechler@stat.math.ethz.ch>
29    
30            * DESCRIPTION (Version): 0.9975-10 to upload
31    
32            * tests/Class+Meth.R (tstMatrixClass): require coercions to
33            specific classes less unconditionally.
34    
35            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
36    
37            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
38    
39            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
40            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
41            R_to_CMatrix segfaults on one platform.
42            Eliminate most coercion method to *specific* classes, and replace
43            with virtual classes coercions.
44    
45    
46    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
47    
48            * src/init.c: export the CHM...._validate() placeholders, since
49            they *are* called.
50    
51            * tests/Class+Meth.R (classCanCoerce): and starting to test
52            all as(<from>, <to>)
53    
54    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>

81              and more of "!", "&", "|", all, any; coercions
82    
83            * R/Rsparse.R: many coercions (which enable quite a few other
84            methods), thanks to enhancements in
85            * src/dgCMatrix.c (R_to_CMatrix): new, and
86            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
87            symmetric & triangular and ..RMatrix objects.
88    
89            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):

97    
98            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
99            where sensible when the <numeric> is of length > 1.
100

111    
112            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
113    
114            * R/Ops.R ("Logic"): and other "Ops", many updates
115    
116    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
117    
118            * src/Mutils.h (SET_DimNames): new utility
119    
120            * R/Auxiliaries.R (nnzero): improved and now exported via

122            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
123    
124    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
125

127    
128    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
129    
130            * R/Auxiliaries.R (as_Csparse): and quite a few others:
131                    allow to pass class definition --> speedup
132            * R/sparseMatrix.R: apply the above
133    
134            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
135    
136            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
137            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
138            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
139    
140            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
141    
142            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
143            and use it for "sparse*" as well, since it's faster than the
144            as_Csparse(.) way.
145    
146    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
147    
148            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.

153            as method for   M[ ij ] <- v
154            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
155    
156            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
157            FALSE answer
158    
159            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
160            * tests/indexing.R: test it, and some of the above
161    
162    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

167    
168          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale
169

171    
172            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
173            base::as.matrix to (x, ...)
174

176    
177          * 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
