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>

55    
56            * R/Rsparse.R: many coercions (which enable quite a few other
57            methods), thanks to enhancements in

59            * src/dgCMatrix.c (compressed_to_TMatrix): now for (d,l,n) ,

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

114    
115            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
