1    2006-12-22  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Auxiliaries.R (as_Csparse2, as_geSimpl): new functions;
4                    also more general diagU2N().
5    
6    2006-12-21  Martin Maechler  <maechler@stat.math.ethz.ch>
7    
8            * R/bind2.R: new file for all cbind2(), rbind() methods moved here
9            from R/<foo>Matrix.R files. Better diagonal & improved sparse methods.
10    
11    2006-12-20  Martin Maechler  <maechler@stat.math.ethz.ch>
12    
13            * tests/bind.R: a few more cases

18            * R/Tsparse.R (replTmat): final(?!) fix for "[<-" ..
19            * tests/indexing.R
20            * tests/indexing.Rout.save: updated

28    
29            * R/sparseMatrix.R (prSpMatrix): "." alignment much improved:
30            align with proper position of "0", i.e., right for integers.
31            argument 'align' by default is "fancy".
32    
33    2006-12-14  Martin Maechler  <maechler@stat.math.ethz.ch>
34    
35            * R/sparseMatrix.R: delegate "Compare" to "Csparse.."

55    
56            * src/CHMfactor.c (CHMfactor_to_sparse): change LDL factorization
57            to LL before converting to a sparse matrix. (The LDL form can be
58            converted to a sparse matrix but it is implicitly a unit
