# Line 1  Line 1 
1    2008-08-23  Douglas Bates <bates@stat.wisc.edu>
2    
3            * [r2243] R/CHMfactor.R, man/CHMfactor-class.Rd: Added expand method and
4              documentation for CHMfactor class
5            * [r2241] R/CHMfactor.R: Added trivial coercion method for CHMfactor ->
6              pMatrix
7    
8    2008-08-19  Martin Maechler  <maechler@stat.math.ethz.ch>
9    
10            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
11    
12    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
13    
14            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
15            variable assignments {from "next version" codetools}.
16            * R/Csparse.R, R/Tsparse.R: ditto
17    
18    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
19    
20            * R/sparseVector.R (sp2vec, coerce to sparseVector):
21            make sure no integer overflows happen, and use double precision
22            (n, index) where appropriate.
23    
24            * tests/Simple.R: test "large" sparse vectors.
25    
26    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
27    
28            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
29            just integer (allowing much longer length).
30    
31    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
32    
33            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
34            "denseMatrix".  This renders "scarceMatrix" dispensable and
35            invalidates part of MM's presentations on "space of Matrix
36            classes", but seems cleaner overall.
37    
38            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
39            "sparseMatrix" in method signatures;
40            further, instead of coercing to "sparseMatrix", coerce to
41            "TsparseMatrix" now.
42    
43    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
44    
45            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
46            .Call(.)
47            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
48    
49    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
50    
51            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
52            recursion in new test in
53            * tests/matprod.R: testing the above and another solve() case, below
54    
55            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
56            e.g. triangular 'x'.
57    
58            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
59            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
60            correctly with unit-triangular x
61    
62            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
63            instead of not checking diagU.
64    
65            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
66            experiments where diagonalMatrix would extend sparse*.
67    
68    
69    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
70    
71            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
72            "x@p[ncol(x)]" instead of length(x@i).
73            * R/Auxiliaries.R (nnzero): ditto
74    
75            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
76            since that fails for over-allocated i.
77    
78            * tests/validObj.R: more testing of over-allocated (i,x) slots
79    
80    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
81    
82            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
83            'sort_in_place' and set it to TRUE in call from
84            * src/Csparse.c (Csparse_validate): sort in place, making sure that
85            validObject() continues sort the columns if needed.
86    
87            * tests/validObj.R: now tests that more thoroughly, and
88            * man/CsparseMatrix-class.Rd: documents it.
89

94            * [r2231] src/chm_common.c: check for sorted columns in
95              as_cholmod_sparse instead of assuming it
96            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
97              expanding diagonal
98    
99

123            boolean argument 'check_Udiag' (formerly implicitly was FALSE).
124

1101    
1102            * R/colSums.R: new file for all (col|row)(Sums|Means) methods,
1103              notably the new ones building on the new .Call(.)s:
1104    
1105            * src/dgCMatrix.c (DEF_gCMatrix_COLSUMS): use to define
1106            all 4 of [dlin]gCMatrix_colSums().

1109    
1110            * [r4472] src/Syms.h, src/init.c: Added Matrix_lengthSym
1111            * [r4473] src/dgCMatrix.c: Modified dgCMatrix_colSums for sparseVector
1112              result
1113    
1114    2007-06-16  Martin Maechler  <maechler@stat.math.ethz.ch>
1115    
1116            * R/kronecker.R: fix typo (could lead to inf.recursion)
1117            * test/simple.R: testing that
1118    
1119            * R/sparseMatrix.R (prSpMatrix): change to be used as print()
1120            method as well (which can have arguments, show() can't).
1121    
1122    2007-06-16 15:52  Douglas Bates <bates@stat.wisc.edu>
1123    
1124            * [r4466] R/dgCMatrix.R, src/dgCMatrix.c, src/dgCMatrix.h, src/init.c:

1133              class
1134            * [r4463] R/sparseMatrix.R, man/dgCMatrix-class.Rd,
1135              man/sparseMatrix-class.Rd: Don't need an "indicators" class - use the
1136              row names to store the levels - duh!  Added an example.
1137    
1138    2007-06-14  Martin Maechler  <maechler@stat.math.ethz.ch>
1139    
1140            * src/Csparse.c (Csparse_validate): check for *repeated* entries
1141            thanks to example from Christian Buchta; with a test here:
1142            * tests/simple.R:
1143

1145    
1146            * R/Auxiliaries.R (callGeneric): another fix, needed for some cases

1150    
1151            * R/lsparseMatrix.R, R/ldenseMatrix.R (all, any): change default to
1152            'na.rm = FALSE' as "everywhere" else in R.
1153    
1154    2007-06-05 Douglas Bates <bates@stat.wisc.edu>

1170            suppressed column names.
1171    
1172    2007-06-04 17:13  Douglas Bates <bates@stat.wisc.edu>
1173    
1174            * [r4418] src/Csparse.c, src/HBMM.c, src/Mutils.c, src/Mutils.h,
1175              src/Tsparse.c, src/chm_common.c, src/chm_common.h, src/dgCMatrix.c,

1187    
1188            * [r4412] inst/include/Matrix_stubs.c, inst/include/cholmod.h,

1191    2007-05-23  Martin Maechler  <maechler@stat.math.ethz.ch>
1192    
1193            * NAMESPACE: exported drop0(), since
1194            * man/drop0.Rd: I have seen several cases, I really wanted to use
1195            it, so our users may want too.
1196    
1197    2007-05-22  Martin Maechler  <maechler@stat.math.ethz.ch>
1198    
1199            * man/colSums.Rd: separately document colSums() etc, since these
1200            have the extra argument 'sparseResult'.
