1    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Tsparse.R ([): more care when subsetting triangular Tsparse
4            * tests/indexing.R: tested now
5            * tests/indexing.Rout.save: updated
6    
7            * src/Csparse.c (Csparse_to_dense): use Rkind = -1 for PATTERN to
8            * src/chm_common.c (chm_dense_to_SEXP): return "ngeMatrix" when
9            appropriate.
10    
11            * NAMESPACE: export a trivial
12            * R/Matrix.R: drop() Matrix-method
13    
14            * R/AllClass.R: moved all prototypes to virtual super classes.
15    
16            * R/Rsparse.R: many more coercions to have less exceptions in
17            * tests/Class+Meth.R:
18    
19            * R/Ops.R (Compare): tweak for case with NA
20            * tests/simpl.R: hence another 'FIXME' eliminated
21    
22    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
23    
24            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
25            objects.
26    
27            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
28              and more of "!", "&", "|", all, any; coercions
29    
30            * R/Rsparse.R: many coercions (which enable quite a few other
31            methods), thanks to enhancements in
32            * src/dgCMatrix.c (R_to_CMatrix): new, and
33            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
34            symmetric & triangular and ..RMatrix objects.
35    
36            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
37            renamed file from src/dsTMatrix.c;
38            now dealing with symmetric and triangular Tsparse coercions, both
39            to dense and general.
40    
41    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
42    
43            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
44    
45            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
46            where sensible when the <numeric> is of length > 1.
47    
48    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
49    
50            * R/Matrix.R ([<-): for M[] <- value: fix length

58    
59            * R/triangularMatrix.R: new file; simple triu() and tril() methods.
60    
61            * R/Ops.R ("Logic"): and other "Ops", many updates
62    
63    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
64    
65            * src/Mutils.h (SET_DimNames): new utility
66    
67            * R/Auxiliaries.R (nnzero): improved and now exported via

74    
75    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
76    
77            * R/Auxiliaries.R (as_Csparse): and quite a few others:
78                    allow to pass class definition --> speedup
79            * R/sparseMatrix.R: apply the above
80    
81            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
82    
83            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
84            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
85            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
86    
87            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
88    
89            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
90            and use it for "sparse*" as well, since it's faster than the
91            as_Csparse(.) way.
92    
93    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>

100            as method for   M[ ij ] <- v
101            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
102    
103            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
104            FALSE answer
105    
106            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
107            * tests/indexing.R: test it, and some of the above
108

122    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
123    
124            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
125            file; start using "Logic", hence
126    
127            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")

216            to LL before converting to a sparse matrix. (The LDL form can be
217            converted to a sparse matrix but it is implicitly a unit

219    
220    2006-12-09  Douglas Bates  <bates@stat.wisc.edu>
221    
222            * src/chm_common.c (chm_factor_to_SEXP): allocate and fill the Dim slot.
