360    
361            * tests/Class+Meth.R (tstMatrixClass): require coercions to
362            specific classes less unconditionally.

365    
366            * R/Tsparse.R (triu): etc, use as(*, "TsparseMatrix") instead of as_Tsparse()
367    
368            * R/Rsparse.R (.R.2.T): R-level workaround using compressed_to_TMatrix.
369            * R/Rsparse.R (.R.2.C): R-level workaround since C-level
370            R_to_CMatrix segfaults on one platform.
371            Eliminate most coercion method to *specific* classes, and replace
372            with virtual classes coercions.

461            * R/sparseMatrix.R: apply the above
462    
463            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
464

725            * R/dgCMatrix.R: solve(a, b="missing") based on
726            * src/dgCMatrix.c (dgCMatrix_matrix_solve): extend to work with
727            RHS = NULL.
728    
729            * R/diagMatrix.R (diagdiagprod): extend %*% etc to ldiMatrix;
730            add more (needed) [t]crossprod() methods.
731    
732            * man/ddiMatrix-class.Rd: more info, notably on 'diag'
733    
734            * R/Auxiliaries.R (as_CspClass): cleanup
735            (drop0): internal utility for "Csparse_drop(*, 0)"
736            (.bail.out.2): encourage active feedback

738    2006-10-26  Martin Maechler  <maechler@stat.math.ethz.ch>
739    
740            * R/dMatrix.R(Compare): new(), then slots [no validity check]
741    
742            * src/Csparse.c (Csparse_validate): fixed (and more efficient in
743            non-valid or 'sorted' case).
744    
745            * R/dsparseMatrix.R: add "chol" method.
746            * R/ddenseMatrix.R: ditto
747    
748            * R/diagMatrix.R (Ops): group methods for  <diagonal> o <sparse>
749            * NAMESPACE (Ops)
750            * R/diagMatrix.R (diag2T): simple utility used "higher level"
751            coercion; deprecating direct lower level coercions.
752    
753            * R/*.R (seq): use seq_len() and seq_along() where possible.

759    
760    2006-10-20  Douglas Bates  <bates@stat.wisc.edu>
761    
762            * src/init.c (R_init_Matrix): export more cholmod CCallable functions.

765    
766          * R/AllClass.R (corMatrix): add 'validity' check;          * R/AllClass.R (corMatrix): add 'validity' check;
