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

58            appropriate.

66            * tests/Class+Meth.R:
67    
68            * R/Ops.R (Compare): tweak for case with NA
69            * tests/simpl.R: hence another 'FIXME' eliminated

71    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
72    
73            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
74            objects.
75    
76            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
77              and more of "!", "&", "|", all, any; coercions
78    
79            * R/Rsparse.R: many coercions (which enable quite a few other
80            methods), thanks to enhancements in
81            * src/dgCMatrix.c (R_to_CMatrix): new, and
82            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
83            symmetric & triangular and ..RMatrix objects.
84    
85            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):

90    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
91    
92            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
93    
94            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
95            where sensible when the <numeric> is of length > 1.

107    
108            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
109    
110            * R/Ops.R ("Logic"): and other "Ops", many updates
111    
112    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
113    
114            * src/Mutils.h (SET_DimNames): new utility
115    
116            * R/Auxiliaries.R (nnzero): improved and now exported via

118            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
119    
120    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
121    
122            * R/diagMatrix.R (!): fix typo.

124    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
125    
126            * R/Auxiliaries.R (as_Csparse): and quite a few others:
127                    allow to pass class definition --> speedup
128            * R/sparseMatrix.R: apply the above
129    
130            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
131    
132            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
133            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
134            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
135    
136            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
137    
138            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
139            and use it for "sparse*" as well, since it's faster than the
140            as_Csparse(.) way.
141    
142    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
143    
144            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.

149            as method for   M[ ij ] <- v
150            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
151    
152            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
153            FALSE answer
154    
155            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
156            * tests/indexing.R: test it, and some of the above
157    
158    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

160            * R/Auxiliaries.R (is_duplicatedT): new utility

163    
164          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale
165

167    
168            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
169            base::as.matrix to (x, ...)

172    
173          * 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
