2    
3            * R/Ops.R (Arith): make sure Csparse o Csparse also works for e.g. ntCMatrix
4            * tests/simple.R: test the above and some of these coercions:
5    
6            * R/nsparseMatrix.R: coercing "Csparse" to "lsparseMatrix";
7                    be careful to avoid infinite recursion, using new coercions in
8            * R/ngCMatrix.R and nsC... and ntC...
9            * R/lsparseMatrix.R: ditto
10    
11            * R/SparseM-conv.R: more conversion, notably for triplet matrices.
12    
13            * src/dgCMatrix.c (R_to_C_Matrix): port Doug's fix and
14            * R/Rsparse.R: reactivate .Call()s
15    
16            * tests/Class+Meth.R: a bit more on actual classes
17    
18    2007-02-04  Douglas Bates  <bates@stat.wisc.edu>
19    
20            * src/dgCMatrix.c (compressed_to_TMatrix): fix memory bug using strdup()
21

23    
24            * DESCRIPTION (Version): 0.9975-10 to upload
25    
26            * tests/Class+Meth.R (tstMatrixClass): require coercions to
27            specific classes less unconditionally.
28    
29            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
30    
31            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
32    
33            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
34            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
35            R_to_CMatrix segfaults on one platform.
36            Eliminate most coercion method to *specific* classes, and replace
37            with virtual classes coercions.
38    
39    
40    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
41    
42            * src/init.c: export the CHM...._validate() placeholders, since
43            they *are* called.
44    
45            * tests/Class+Meth.R (classCanCoerce): and starting to test
46            all as(<from>, <to>)

75              and more of "!", "&", "|", all, any; coercions
76    
77            * R/Rsparse.R: many coercions (which enable quite a few other
78            methods), thanks to enhancements in
79            * src/dgCMatrix.c (R_to_CMatrix): new, and
80            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,

109    
110    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
111    
112            * src/Mutils.h (SET_DimNames): new utility
113    
114            * R/Auxiliaries.R (nnzero): improved and now exported via

117    
118    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
119

122    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
123    
124            * R/Auxiliaries.R (as_Csparse): and quite a few others:
125                    allow to pass class definition --> speedup
126            * R/sparseMatrix.R: apply the above
127    
128            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
129    
130            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
131            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
132            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
133    
134            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
135    
136            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
137            and use it for "sparse*" as well, since it's faster than the
138            as_Csparse(.) way.
139    
140    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>

149    
150            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
151            FALSE answer
152    
153            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
154            * tests/indexing.R: test it, and some of the above
155

172            file; start using "Logic", hence
173    
174            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
175            * NAMESPACE: import and export "Logic"
176    
177    2006-12-27  Martin Maechler  <maechler@stat.math.ethz.ch>
178
