116            with virtual classes coercions.
117    
118    
119    2007-02-01  Martin Maechler <maechler@stat.math.ethz.ch>

214    
215            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

232            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
233            * tests/indexing.R: test it, and some of the above
