4            * src/dgCMatrix.c (R_to_CMatrix, compressed_to_TMatrix): remove
5            const modifier on declaration of the array 'valid'
6    
7    2007-02-12  Douglas Bates  <bates@stat.wisc.edu>
8

12    
13            * DESCRIPTION (Date, Version): 0.9975-10 with new date.
14    
15            * R/Ops.R (Arith): make sure Csparse o Csparse also works for e.g. ntCMatrix
16            * tests/simple.R: test the above and some of these coercions:
17    
18            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
19                    be careful to avoid infinite recursion, using new coercions in
20            * R/ngCMatrix.R and nsC... and ntC...
21            * R/lsparseMatrix.R: ditto
22    
23            * R/SparseM-conv.R: more conversion, notably for triplet matrices.
24    
25            * src/dgCMatrix.c (R_to_C_Matrix): port Doug's fix and
26            * R/Rsparse.R: reactivate .Call()s
27    
28            * tests/Class+Meth.R: a bit more on actual classes
29

35    
36            * DESCRIPTION (Version): 0.9975-10 to upload
37    
38            * tests/Class+Meth.R (tstMatrixClass): require coercions to
39            specific classes less unconditionally.
40    
41            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
42    
43            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
44    
45            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
46            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
47            R_to_CMatrix segfaults on one platform.
48            Eliminate most coercion method to *specific* classes, and replace
49            with virtual classes coercions.
50    
51    
52    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
53    
54            * src/init.c: export the CHM...._validate() placeholders, since
55            they *are* called.
56    
57            * tests/Class+Meth.R (classCanCoerce): and starting to test
58            all as(<from>, <to>)
59

88    
89            * R/Rsparse.R: many coercions (which enable quite a few other
90            methods), thanks to enhancements in

92            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
93            symmetric & triangular and ..RMatrix objects.
94    
95            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):

103    
104            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
105            where sensible when the <numeric> is of length > 1.
106

117    
118            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
119    
120            * R/Ops.R ("Logic"): and other "Ops", many updates
121    
122    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
123    
124            * src/Mutils.h (SET_DimNames): new utility
125    
126            * R/Auxiliaries.R (nnzero): improved and now exported via

129    
130    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
131

134    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
135    
136            * R/Auxiliaries.R (as_Csparse): and quite a few others:
137                    allow to pass class definition --> speedup
138            * R/sparseMatrix.R: apply the above
139    
140            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
141    
142            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
143            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
144            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
145    
146            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
147    
148            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
149            and use it for "sparse*" as well, since it's faster than the
150            as_Csparse(.) way.
151    
152    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>

161    
162            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
163            FALSE answer
164    
165            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
166            * tests/indexing.R: test it, and some of the above
167    
168    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

173    
174          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale

177    
178            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
179            base::as.matrix to (x, ...)
