50    
51            * src/dgCMatrix.c (dgCMatrix_LU): partially revert change

70    
71            * R/nsCMatrix.R (setAs(., dgTMatrix))): remove unused method
72    
73    2008-08-18  Martin Maechler  <maechler@stat.math.ethz.ch>
74    
75            * R/Ops.R (.Ops2dge.via.x, and many others): eliminate never-used
76            variable assignments {from "next version" codetools}.
77            * R/Csparse.R, R/Tsparse.R: ditto
78    
79    2008-08-17  Martin Maechler  <maechler@stat.math.ethz.ch>
80    
81            * R/sparseVector.R (sp2vec, coerce to sparseVector):
82            make sure no integer overflows happen, and use double precision
83            (n, index) where appropriate.
84    
85            * tests/Simple.R: test "large" sparse vectors.
86    
87    2008-08-14  Martin Maechler  <maechler@stat.math.ethz.ch>
88    
89            * R/AllClass.R (sparseVector): 'length' and 'i' are "numeric", not
90            just integer (allowing much longer length).
91    
92    2008-07-28  Martin Maechler  <maechler@stat.math.ethz.ch>
93    
94            * R/AllClass.R (diagonalMatrix): extend  "sparseMatrix" instead of
95            "denseMatrix".  This renders "scarceMatrix" dispensable and
96            invalidates part of MM's presentations on "space of Matrix
97            classes", but seems cleaner overall.
98    
99            * R/diagMatrix.R, etc: eliminate "scarceMatrix", replacing it by
100            "sparseMatrix" in method signatures;
101            further, instead of coercing to "sparseMatrix", coerce to
102            "TsparseMatrix" now.
103    
104    2008-07-26  Martin Maechler  <maechler@stat.math.ethz.ch>
105    
106            * src/dgCMatrix.c (dgCMatrix_qrsol): allow third argument 'order' in
107            .Call(.)
108            * R/sparseMatrix.R (lm.fit.sparse), src/dgCMatrix.h, src/init.c: ditto
109    
110    2008-07-24  Martin Maechler  <maechler@stat.math.ethz.ch>
111    
112            * R/dgeMatrix.R: need solve(<dge>, <sparse>) against infinite
113            recursion in new test in
114            * tests/matprod.R: testing the above and another solve() case, below
115    
116            * R/sparseMatrix.R (lm.fit.sparse): slightly more efficient for
117            e.g. triangular 'x'.
118    
119            * src/dgCMatrix.c (dgCMatrix_qrsol): use AS_CSP() hence allowing dtC*
120            * src/dgCMatrix.c (dgCMatrix_cholsol): use AS_CHM_SP() to work
121            correctly with unit-triangular x
122    
123            * src/dsCMatrix.c (dsCMatrix_Csparse_solve): use AS_CHM_SP()
124            instead of not checking diagU.
125    
126            * R/diagMatrix.R, R/Auxiliaries.R: tweaks to allow later
127            experiments where diagonalMatrix would extend sparse*.
128    
129    
130    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
131    
132            * src/dgCMatrix.c (compressed_non_0_ij): for nnzero(), use
133            "x@p[ncol(x)]" instead of length(x@i).
134            * R/Auxiliaries.R (nnzero): ditto
135    
136            * src/chm_common.c (as_cholmod_sparse): Do not use LENGTH(islot)
137            since that fails for over-allocated i.
138    
139            * tests/validObj.R: more testing of over-allocated (i,x) slots
140    
141    2008-07-23  Martin Maechler  <maechler@stat.math.ethz.ch>
142    
143            * src/chm_common.c (as_cholmod_sparse): Add 4th argument
144            'sort_in_place' and set it to TRUE in call from
145            * src/Csparse.c (Csparse_validate): sort in place, making sure that
146            validObject() continues sort the columns if needed.
147    
148            * tests/validObj.R: now tests that more thoroughly, and
149            * man/CsparseMatrix-class.Rd: documents it.
150

152    
153            * [r2233] src/chm_common.c: sort columns more carefully in
154              as_cholmod_sparse
155            * [r2231] src/chm_common.c: check for sorted columns in
156              as_cholmod_sparse instead of assuming it
157            * [r2228] src/cs_utils.c: Use R_alloc for semi-permanent storage when
158              expanding diagonal
159

294            * src/Mutils.c (m_encodeInd, m_encodeInd2):
295            * R/*.R: .Call(m_encodeInd2?, ..) instead of encodeInd2?(..).

1444            they *are* called.
1445    
1446            * tests/Class+Meth.R (classCanCoerce): and starting to test
1447            all as(<from>, <to>)

1476              and more of "!", "&", "|", all, any; coercions
1477    
1478            * R/Rsparse.R: many coercions (which enable quite a few other
1479            methods), thanks to enhancements in

1485            renamed file from src/dsTMatrix.c;

1488    
1489    2007-01-27  Martin Maechler  <maechler@stat.math.ethz.ch>

1492    
1493            * R/Ops.R (Arith): <dgCMatrix> o <numeric> now remains sparse
1494            where sensible when the <numeric> is of length > 1.
1495    
1496    2007-01-26  Martin Maechler  <maechler@stat.math.ethz.ch>
1497    
1498            * R/Matrix.R ([<-): for M[] <- value: fix length

1508    
1509            * R/Ops.R ("Logic"): and other "Ops", many updates
1510    
1511    2007-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>
1512    
1513            * src/Mutils.h (SET_DimNames): new utility
1514    
1515            * R/Auxiliaries.R (nnzero): improved and now exported via
1516    
1517            * NAMESPACE: + nnzero(); length() == prod(dim(.)) method for all "Matrix" objects
1518    
1519    2007-01-17  Martin Maechler  <maechler@stat.math.ethz.ch>
1520

1523    2007-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
1524    
1525            * R/Auxiliaries.R (as_Csparse): and quite a few others:
1526                    allow to pass class definition --> speedup
1527            * R/sparseMatrix.R: apply the above
1528    
1529            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
1530    
1531            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
1532            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of
1533            old dup_mMatrix_as_dgeMatrix), eliminating a long-standing "FIXME".
1534    
1535            * src/dense.c (dense_to_Csparse): use new mMatrix_as_geMatrix()
1536    
1537            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,
1538            and use it for "sparse*" as well, since it's faster than the
1539            as_Csparse(.) way.
1540    
1541    2007-01-15  Martin Maechler  <maechler@stat.math.ethz.ch>
1542    
1543            * R/Ops.R ("Logic"): more methods, notably an  <lgC> o <lgC> one.

1548            as method for   M[ ij ] <- v
1549            * R/Csparse.R:: go via Tsparse for "M[ij] <- v"
1550    
1551            * R/Ops.R: "Compare" for (C|R)sparse: need pointer slot for all
1552            FALSE answer
1553    
1554            * R/Csparse.R (replCmat): fix the "all non-zero" case with reordering
1555            * tests/indexing.R: test it, and some of the above
1556    
1557    2007-01-05  Martin Maechler  <maechler@stat.math.ethz.ch>
1558    
1559            * R/Auxiliaries.R (is_duplicatedT): new utility

1562    
1563          * src/init.c (R_init_Matrix): export cholmod_scale          * src/init.c (R_init_Matrix): export cholmod_scale
1564    
1565    2006-12-30  Martin Maechler  <maechler@stat.math.ethz.ch>
1566    
1567            * R/zzz.R (tmp): for R >= 2.5.0, extend formals of our
1568            base::as.matrix to (x, ...)
1569    
1570  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>  2006-12-28  Martin Maechler  <maechler@stat.math.ethz.ch>
1571    
1572          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R          * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
