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

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

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

137    
138            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

151    
152            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
153            FALSE answer

171    2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
172    
173            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
174            file; start using "Logic", hence
175    
176            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
177            * NAMESPACE: import and export "Logic"
178

265            to LL before converting to a sparse matrix. (The LDL form can be
266            converted to a sparse matrix but it is implicitly a unit
267            triangular matrix and a diagonal matrix overwritten on the diagonal.)
268
