383            * R/symmetricMatrix.R: setAs(., "symmetricMatrix")
384    
385            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
386            order to match the generic (and evade .local(..)).
387    
388            * R/dsCMatrix.R: dgC -> dsC: use C code!
389    
390            * NAMESPACE, R/AllGeneric.R (symmpart, skewpart): new functions

408            * tests/simple.R: test the fix above
409

412    
413            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()

427                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
428

430            * src/Tsparse.h, init.c: ditto
431            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse

449            coercion to "nMatrix" and "pMatrix"
450

467            * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
468                    in order to ensure 'system = *' is not lost;
469                    formals()$system instead of cut&paste.
470            * tests/factorizing.R: test solve(<CHM..>, <numeric>)
471
