1    2006-12-15  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/sparseMatrix.R (prSpMatrix): "." alignment much improved:
4            align with proper position of "0", i.e., right for integers.
5            argument 'align' by default is "fancy".
6    
7    2006-12-14  Martin Maechler  <maechler@stat.math.ethz.ch>
8    
9            * R/sparseMatrix.R: delegate "Compare" to "Csparse.."
10            * R/Csparse.R: and fix "Compare" for more cases.
11            * tests/Class+Meth.R: test some of these (m == m, m != m)

18    
19            * man/all-methods.Rd: document them minimally
20    
21            * tests/simple.R: add a few examples for these

31            to LL before converting to a sparse matrix. (The LDL form can be
32            converted to a sparse matrix but it is implicitly a unit
33            triangular matrix and a diagonal matrix overwritten on the diagonal.)
34    
35    2006-12-09  Douglas Bates  <bates@stat.wisc.edu>
