3            * R/dtCMatrix.R,dgCMatrix.R,Csparse.R src/init.c,dgCMatrix.[ch],
4            Csparse.[ch],chm_common.c,dense.c : Use CHOLMOD code and methods
5            for CsparseMatrix, TsparseMatrix, denseMatrix or matrix when
6            possible.

18    
19            * src/lmer.c: adjust checks in glmer_init for S4SXP

62            * DESCRIPTION (Version): 0.995-13 to be released to CRAN
63    
64            * DESCRIPTION (Lazydata): no, instead of 'yes' because it fails for:

66            * data/KNex.R, inst/external/KNex_slots.rda: replacing data/KNex.rda

127

141            * tests/indexing.R: test it.
142

159    
160    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
161    
162            * tests/simple.R: add check for correct dsT -> dgT coercion;
163                    add check for correct printing of symmetric sparse matrices.
164    
165            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
166            for sparse symmetric matrices.

186    
187            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
188                 ==> construction of illegal "*gTMatrix" via new() should
189                 now be much less easy:
190            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
191    
192            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
193                    directly.

232    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
233    
234            * R/dgTMatrix.R (colSums): etc. All four of
235            colSums(), rowSums(), colMeans(), rowMeans() now should work for
236            all "Matrices".

239    
240            * R/lmer.R (panel.ci): Add a reference line at zero and a
241            background grid to the qqmath plot of ranef.lmer.

244    
245            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
246            grouping factors to be specified in the formula as (1|foo/bar).

249    
250            * R/lmer.R (findbars and others): Change check of is.numeric to
251            !is.language to resolve the bug reported by Jacob Wegelin.
252    
253            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
254            code to evaluate inbreeding coefficients without calculating T,
255            based on code in Sargolzaei and Iwaisaki's paper.

259            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
260            generic and mer methods for isNested and denomDF. This denomDF was
261            an attempt to emulate that in lme but I don't think that makes
262            sense.  Use the trace of the hat matrix instead.
263    
264    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
265    
266            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

269    
270

277    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
278    
279            * R/pedigree.R (pedigree): Replace sire and dam values outside the
280            allowable range with NAs. Added a corresponding check in the
281            validity check for the pedigree class.
282    
283            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
284            crossprod methods now inherits from symmetricMatrix.

287    
288            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
289            generics lowerTriMatrix and upperTriMatrix along with methods for
290            the Csparse virtual class.  Also added a C function Csparse_band
291            that implements these methods by calling cholmod_band.
292    
293    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
294    
295            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
296            erased when it was NULL.  This led to invalid subselections!
297    
298    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
299    
300            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
301            in method for "t" so as not to lose the unit diagonal property.
302    
303    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
304    
305            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
306            and methods.  This is now an option to the ranef method for the
307            mer class.
308    
309            * src/cs_utils.c: Ensure that the nz component is -1 for a
310            compressed column-oriented matrix.  Minor formatting cleanup.
311

313            objects.
314

316    
317            * R/Auxiliaries.R (diagU2N): new for the solve() methods in

321    
322            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
323            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].

338    
339    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>

348    
349            * R/dtCMatrix.R: allow coercion from  dgC* to triangular (dtC*)
