# Line 1  Line 1 
1    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use
4            the C code depending on a slot structure that's no longer valid.
5            * src/dgTMatrix.c: dito (also: src/init.c src/dgTMatrix.h)
6    
7    
8    2006-05-17  Douglas Bates  <bates@stat.wisc.edu>
9    
10            *  R/{AllGeneric.R,Csparse.R},man/band.Rd,NAMESPACE: changed name
11            of lowerTriMatrix generic and methods to tril (also upper to triu)
12            and added a general band extractor.
13    
14    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
15    
16            * R/pedigree.R (pedigree): Replace sire and dam values outside the
17            allowable range with NAs. Added a corresponding check in the
18            validity check for the pedigree class.
19    
20            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
21            crossprod methods now inherits from symmetricMatrix.
22    
23    2006-05-15  Douglas Bates  <bates@stat.wisc.edu>
24    
25            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
26            generics lowerTriMatrix and upperTriMatrix along with methods for
27            the Csparse virtual class.  Also added a C function Csparse_band
28            that implements these methods by calling cholmod_band.
29    
30    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
31    
32            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
33            erased when it was NULL.  This led to invalid subselections!
34    
35    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
36    
37            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
38            in method for "t" so as not to lose the unit diagonal property.
39    
40    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
41    
42            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
43            and methods.  This is now an option to the ranef method for the
44            mer class.
45    
46            * src/cs_utils.c: Ensure that the nz component is -1 for a
47            compressed column-oriented matrix.  Minor formatting cleanup.
48    
49            * man/lmer-class.Rd: Document the qqmath method for ranef.lmer
50            objects.
51    
52    2006-04-19  Martin Maechler  <maechler@stat.math.ethz.ch>
53    
54            * R/Auxiliaries.R (diagU2N): new for the solve() methods in
55            * R/dtCMatrix.R: where dgC -> dgT coercion now preserves diag = "U".
56    
57    2006-04-15  Douglas Bates  <bates@stat.wisc.edu>
58    
59            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
60            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].
61    
62            * R/dtCMatrix.R, src/dtCMatrix.[ch] : CSparse-based solve methods
63            for the dtCMatrix class.
64    
65    2006-04-12  Douglas Bates  <bates@stat.wisc.edu>
66    
67            * R/pedigree.R, R/AllClass.R, NAMESPACE: added a pedigree class
68            and methods for it.
69    
70    2006-04-12  Martin Maechler  <maechler@stat.math.ethz.ch>
71    
72            * R/dgCMatrix.R: add  storage.mode(.) <- "double" for "matrix"
73            arguments, such that M %*% 1:6 now works
74            * Tests/matprod.R: test the above
75    
76    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>
77    
78            * R/lmer.R (qqmath,ranef.lmer-method): added a qqmath method for
79            the ranef.lmer class.
80    
81            * R/AllClass.R, NAMESPACE, R/lmer.R: Added a postVar generic and
82            methods to extract the posterior variances from the bVar slot.
83    
84    2006-03-30  Martin Maechler  <maechler@stat.math.ethz.ch>
85    
86            * R/dtCMatrix.R: allow coercion from  dgC* to triangular (dtC*)
87            * R/dsCMatrix.R: and symmetric (dsC*) 'Csparse' matrices.
88    
89            * R/Tsparse.R: Tsparse* -> Csparse* coercion now works and is tested in
90            * tests/simple: (extended)
91    
92            * R/sparseMatrix.R (isTriangular): now using much improved
93            * R/Auxiliaries.R (isTriC): new triangularity check for *CMatrix
94    
95  2006-03-23  Douglas Bates  <bates@stat.wisc.edu>  2006-03-23  Douglas Bates  <bates@stat.wisc.edu>
96    
97          * src/dsyMatrix.c (dsyMatrix_as_dspMatrix): Propagate DimNames          * src/dsyMatrix.c (dsyMatrix_as_dspMatrix): Propagate DimNames
