 bCrosstab(): do we really want the diagonal "V:V" crosstabs? 


(if so or in any case: add to man/bCrosstab.Rd ) 





 src/Metis/ : one of the two Makefiles needs fixing, as changing 


src/Metis/*.c does not lead to recompilation. 


DB  it seems both Makefiles need fixing. I think I have the 


src/Metis/Makefile fixed but not src/Makefile

 man/Matrix.Rd : has example with dimnames, but we just drop them! 
 methods for rbind and cbind where they make sense

MM thinks dimnames should be supported (but then ...)

 provide methods for "dspMatrix" and "dppMatrix"! 
43 


44 

 implement (more) methods for supporting "packed" (symmetric / triangular) 
45 

matrices; particularly something like pack() and unpack() [to/from our 
46 

classes from/to "numeric"]  have already man/unpack.Rd but no method yet! 
47 


48 

 implement diagonal Matrix class "ddiMatrix" etc 
49 

using constructor function Diagonal() or Diag().
