1    2007-02-05  Martin Maechler  <maechler@stat.math.ethz.ch>
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    
22    2007-02-03  Martin Maechler  <maechler@stat.math.ethz.ch>
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>)
47    
48    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>
49    
50            * R/Tsparse.R ([): more care when subsetting triangular Tsparse
51            * tests/indexing.R: tested now
52            * tests/indexing.Rout.save: updated
53    
54            * src/Csparse.c (Csparse_to_dense): use Rkind = -1 for PATTERN to
55            * src/chm_common.c (chm_dense_to_SEXP): return "ngeMatrix" when
56            appropriate.
57    
58            * NAMESPACE: export a trivial
59            * R/Matrix.R: drop() Matrix-method
60    
61            * R/AllClass.R: moved all prototypes to virtual super classes.
62    
63            * R/Rsparse.R: many more coercions to have less exceptions in
64            * tests/Class+Meth.R:
65    
66            * R/Ops.R (Compare): tweak for case with NA
67            * tests/simpl.R: hence another 'FIXME' eliminated
68    
69    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
70    
71            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
72            objects.
73    
74            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
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) ,
81            symmetric & triangular and ..RMatrix objects.
82    
83            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
84            renamed file from src/dsTMatrix.c;
85            now dealing with symmetric and triangular Tsparse coercions, both
86            to dense and general.
87    
88    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
89    
90            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
91    
92            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
93            where sensible when the <numeric> is of length > 1.
94    
95    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
96    
97            * R/Matrix.R ([<-): for M[] <- value: fix length
98    
99    2007-01-25  Martin Maechler  <maechler@stat.math.ethz.ch>
100    
101            * R/Auxiliaries.R (n2l_Matrix): new, to be used in
102            * R/ndenseMatrix.R: new coercions n* -> l*
103    
104  2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>  2007-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
105    
106          * R/triangularMatrix.R: new file; simple triu() and tril() methods.          * R/triangularMatrix.R: new file; simple triu() and tril() methods.
