1    2006-09-29  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/Csparse.R (replCmat): improve for missing i / j in non-simple cases
4    
5            * R/lsTMatrix.R: new files w/ missing methods
6            * R/nsTMatrix.R:  "  'for completeness'
7    
8            * tests/Class+Meth.R: a bit less 'not.ok.classes'
9

11    
12    
13    2006-09-28  Douglas Bates  <bates@R-project.org>
14    
15            * src/dppMatrix.h: Ensure definition of dspMatrix_validate is
16            included.

21    2006-09-28  Martin Maechler  <maechler@stat.math.ethz.ch>
22    
23            * DESCRIPTION (Version): 0.9975-1
24    
25            * tests/simple.R: less checks fail; using NA, found that our
26                    kronecker() is not base-compatible with NA's.
27    
28            * R/dMatrix.R: "Compare" method now implemented for all cases
29    
30            * R/Auxiliaries.R (indTri): == which([lower/upper].tri( * )) new utility
31    
32            * man/dtpMatrix-class.Rd: mention length of 'x' slot

51    
52            * R/[CT]sparse.R (crossprod and tcrossprod): Handle the cases for x
53            symmetric and y missing in R code using %*% (cholmod_aat doesn't
54            accept a symmetric matrix).

69            case.
70    
71            * R/Auxiliaries.R (nz.NA): new utility now used in nnzero()
72

79    
80            * R/dMatrix.R ("Compare"): fix to work with NA's
81    
82            * R/AllClass.R: "Cholesky" etc now inherit from MatrixFactorization.
83    
84            * src/lgCMatrix.c (ncsc_to_matrix): renamed from lcsc_to_matrix()
85                    which is implemented.

88    
89            * src/chm_common.c: coerce logical <-> double instead of

98    
99            * R/AllClass.R ("nMatrix"): and subclasses for "nonzero pattern"
100                    Matrices, since "lMatrix", also "lsparseM" can have NA

104            * src/chm_common.c (chm_dense_to_SEXP): and others:
105                    new 'Rkind' argument: "l*" and "d*" both use CHOLMOD_REAL

122            * R/sparseMatrix.R (Tsp2grNEL): do not yet use graph::foo()
123    
124            * R/dgeMatrix.R: do not define tcrossprod() methods for "matrix"

131            * src/Makefile, src/CHOLMOD/Lib/Makefile, src/Metis,CAMD,CCOLAMD:
132            Remove partitioning algorithms for sparse matrix reordering.  The
133            copyright on the Metis code was problematic and the methods were
134            rarely used.
135            * src/triplet_to_col.[ch],MMHB.[ch]: Remove triplet_to_col.  Such
136            operations are now done entirely in CHOLMOD code.

151            (Depends): R (>= 2.4.0)
152    
153    2006-09-01  Douglas Bates  <bates@R-project.org>

158    
159            * R/sparseMatrix.R: add coercion from "ANY" to "sparseMatrix"
160            * R/denseMatrix.R:  add coercion from "ANY" to "denseMatrix"
161    
162            * R/Matrix.R ([): use nargs() to disambiguate M[i] and M[i,]
163    
164    2006-08-31  Martin Maechler  <maechler@stat.math.ethz.ch>
165    
166            * R/sparseMatrix.R (Arith): moved Arith group method one-level up

169            * R/Csparse.R: ditto
170    
171    2006-08-31  Martin Maechler  <maechler@stat.math.ethz.ch>
172    
173            * R/dMatrix.R (Compare): improve availability of "<", etc
174            * R/Auxiliaries.R (asTuniq): new; also make use of R 2.4.x print(*,max)
175    
176    2006-08-30  Martin Maechler  <maechler@stat.math.ethz.ch>
177    
178            * R/dgCMatrix.R: aargh: "Arith(<dgC>, numeric)" was wrong because
179            of a 0-index which was used as 1-index (..hmm)
180    
181            * R/sparseMatrix.R (prSpMatrix): fix printing an all-0 sparse Matrix
182    
183            * R/Auxiliaries.R (all0, is0): for 0-testing in presence of NA's
184            * R/Auxiliaries.R (isTriMat): use all0() for 0-testing.
185            (.is.diagonal): ditto
186    
187            * R/lgTMatrix.R: as("matrix", "lgTMatrix"): warn about NA's
188    
189            * R/Matrix.R (Matrix): also work for NA data

192    
193          * R/Matrix.R (Matrix): + 'forceCheck' argument; dimnames setting          * R/Matrix.R (Matrix): + 'forceCheck' argument; dimnames setting
