2    
3            * tests/bind.R: a few more cases
4            * R/Auxiliaries.R (.M.kind): also work for atomic vectors
5    
6            * R/denseMatrix.R (cbind2/rbind2): moved here (and generalized) from
7            * R/ddenseMatrix.R (cbind2/rbind2)
8            * R/Tsparse.R (replTmat): final(?!) fix for "[<-" ..

18    
19            * R/sparseMatrix.R (prSpMatrix): "." alignment much improved:
20            align with proper position of "0", i.e., right for integers.
21            argument 'align' by default is "fancy".
22    
23    2006-12-14  Martin Maechler  <maechler@stat.math.ethz.ch>
24    
25            * R/sparseMatrix.R: delegate "Compare" to "Csparse.."

47            to LL before converting to a sparse matrix. (The LDL form can be
48            converted to a sparse matrix but it is implicitly a unit
