1    2008-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Matrix.R (.M.sub.i.2col): fix for logical matrix indexing
4            * R/Tsparse.R (.TM.sub.i.2col, .TM.repl.i.2col): ditto;
5                    now, M[lower.tri(M)] and  M[lower.tri(M)] <- v  work better
6    
7            * src/Tsparse.c (Tsparse_to_tCsparse): new fast utility.
8            * src/Tsparse.h, init.c: ditto
9            * R/Auxiliaries.R (isTriT): new; faster than going via Csparse
10                 both isTriC() and isTriT() now return TRUE with "kind" or FALSE.
11            * R/sparseMatrix.R (isTriangular): hence simplified
12    
13    2008-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>
14    
15            * R/Ops.R (.Arith.Csparse): new utility factored out of former
16              <dgC> o <dgC>, extended for triangular and also used in  <dtC> o <dtC>.
17    
18    2008-01-23  Martin Maechler  <maechler@stat.math.ethz.ch>
19    
20            * tests/factorizing.R (checkSchur): and more tests for checking Schur()
21    
22            * inst/test-tools.R (isOrthogonal): new function; also file restructured
23    
24    2008-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
27            coercion to "nMatrix" and "pMatrix"
28    
29            * R/AllClass.R: "Schur" class;  "number" class union
30            * man/number-class.Rd:
31            * man/Schur-class.Rd:
32    
33            * R/eigen.R (.dgeSchur): utility, and return "Schur" class
34            (.simpleSchur): Schur() method for diagonal matrices
35            (.triSchur):    Schur() method for triangular matrices
36            (Schur.sym):    Schur() for symmetric matrices {building on eigen()}.
37    
38

43    2008-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
44    
45            * R/CHMfactor.R (solve): method for b="numeric", but also b="ANY"
46                    in order to ensure 'system = *' is not lost;
47                    formals()$system instead of cut&paste.
48            * tests/factorizing.R: test solve(<CHM..>, <numeric>)
49    
50    2008-01-11  Martin Maechler  <maechler@stat.math.ethz.ch>

57    
58            * R/pMatrix.R: as(*, "matrix") now returns 0/1 *integer* matrix,
59                    and hence does as.vector(.).

67                    and  "[<-" : (x, i,j, ..., value)
68    
69            * R/denseMatrix.R: M[i] and M[i] <- v  (i vector) now work
70            * R/Tsparse.R (replTmat):    ditto
71            * R/diagMatrix.R (replDiag): ditto
72            * R/Csparse.R (replCmat):    ditto {was it worth the pain?}

87            * R/Matrix.R: "generic" cov2cor() method
88    
89            * R/nearPD.R: new 'only.values', 'keepDiag' arguments;

92    
93    2007-12-05  Doug Bates and Martin Maechler
