3            * DESCRIPTION (Version): 0.9975-10 to upload
4    
5            * tests/Class+Meth.R (tstMatrixClass): require coercions to
6            specific classes less unconditionally.
7    
8            * R/Auxiliaries.R: get rid of as_Tsparse() and as_Rsparse()
9    
10            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
11    
12            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
13            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
14            R_to_CMatrix segfaults on one platform.
15            Eliminate most coercion method to *specific* classes, and replace
16            with virtual classes coercions.
17    
18    
19    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>
20    
21            * src/init.c: export the CHM...._validate() placeholders, since
22            they *are* called.
23    
24            * tests/Class+Meth.R (classCanCoerce): and starting to test
25            all as(<from>, <to>)
26    
27    2007-01-30  Martin Maechler  <maechler@stat.math.ethz.ch>
28    
29            * R/Tsparse.R ([): more care when subsetting triangular Tsparse

33            * src/Csparse.c (Csparse_to_dense): use Rkind = -1 for PATTERN to
34            * src/chm_common.c (chm_dense_to_SEXP): return "ngeMatrix" when
35            appropriate.
36    
37            * NAMESPACE: export a trivial
38            * R/Matrix.R: drop() Matrix-method
39

41    
42            * R/Rsparse.R: many more coercions to have less exceptions in
43            * tests/Class+Meth.R:
44    
45            * R/Ops.R (Compare): tweak for case with NA
46            * tests/simpl.R: hence another 'FIXME' eliminated

48    2007-01-29  Martin Maechler  <maechler@stat.math.ethz.ch>
49    
50            * R/diagMatrix.R (solve): the obvious methods for diagonalMatrix
51            objects.
52    
53            * tests/Class+Meth.R (tstMatrixClass): now testing diag(), nnzero(),
54              and more of "!", "&", "|", all, any; coercions
55    
56            * R/Rsparse.R: many coercions (which enable quite a few other
57            methods), thanks to enhancements in
58            * src/dgCMatrix.c (R_to_CMatrix): new, and
59            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,
60            symmetric & triangular and ..RMatrix objects.
61    
62            * src/TMatrix_as.c (Matrix_T_as_DENSE,Matrix_T_as_GENERAL):
63            renamed file from src/dsTMatrix.c;
64            now dealing with symmetric and triangular Tsparse coercions, both
65            to dense and general.
66    
67    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>
68    
69            * src/dsTMatrix.c: has now "l" and "n" methods besides the "d" ones.
70

72            where sensible when the <numeric> is of length > 1.

75    
76            * R/Matrix.R ([<-): for M[] <- value: fix length

88    
89    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
90    
91            * src/Mutils.h (SET_DimNames): new utility
92    
93            * R/Auxiliaries.R (nnzero): improved and now exported via

100    
101    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
102    
103            * R/Auxiliaries.R (as_Csparse): and quite a few others:
104                    allow to pass class definition --> speedup
105            * R/sparseMatrix.R: apply the above
106    
107            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
108    
109            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
110            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
111            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
112    
113            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
114    
115            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
116            and use it for "sparse*" as well, since it's faster than the
117            as_Csparse(.) way.
118    
119    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
120

126            as method for   M[ ij ] <- v
127            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
128    
129            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
130            FALSE answer
131    
132            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
133            * tests/indexing.R: test it, and some of the above
134    
135    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>

146            base::as.matrix to (x, ...)
147    
148    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
149    
150            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
151            file; start using "Logic", hence
152    
153            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
154            * NAMESPACE: import and export "Logic"
155

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