34            * DESCRIPTION (Version): 0.995-13 to be released to CRAN
35    
36            * DESCRIPTION (Lazydata): no, instead of 'yes' because it fails for:

53    
54            * NAMESPACE, src/lmer.c, R/lmer.R (hatTrace):  Add the hatTrace

88    
89            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
90

99

113            * tests/indexing.R: test it.
114    
115            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

133    
134            * tests/simple.R: add check for correct dsT -> dgT coercion;
135                    add check for correct printing of symmetric sparse matrices.
136    
137            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
138            for sparse symmetric matrices.

158    
159            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
160                 ==> construction of illegal "*gTMatrix" via new() should
161                 now be much less easy:
162            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
163    
164            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
165                    directly.

204    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
205    
206            * R/dgTMatrix.R (colSums): etc. All four of
207            colSums(), rowSums(), colMeans(), rowMeans() now should work for
208            all "Matrices".

211

215    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
216    
217            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
218            grouping factors to be specified in the formula as (1|foo/bar).
219

221    
222            * R/lmer.R (findbars and others): Change check of is.numeric to
223            !is.language to resolve the bug reported by Jacob Wegelin.
224    
225            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
226            code to evaluate inbreeding coefficients without calculating T,
227            based on code in Sargolzaei and Iwaisaki's paper.

229    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
230    
231            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
232            generic and mer methods for isNested and denomDF. This denomDF was
233            an attempt to emulate that in lme but I don't think that makes
234            sense.  Use the trace of the hat matrix instead.
235    
236    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
237    
238            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

246            of lowerTriMatrix generic and methods to tril (also upper to triu)
247            and added a general band extractor.
248    
249    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
250    
251            * R/pedigree.R (pedigree): Replace sire and dam values outside the
252            allowable range with NAs. Added a corresponding check in the
253            validity check for the pedigree class.
254    
255            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
256            crossprod methods now inherits from symmetricMatrix.
257    
258    2006-05-15  Douglas Bates  <bates@stat.wisc.edu>
259    
260            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
261            generics lowerTriMatrix and upperTriMatrix along with methods for
262            the Csparse virtual class.  Also added a C function Csparse_band
263            that implements these methods by calling cholmod_band.
264    
265    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
266    
267            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
268            erased when it was NULL.  This led to invalid subselections!
269    
270    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
271    
272            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
273            in method for "t" so as not to lose the unit diagonal property.
274    
275    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
276    
277            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
278            and methods.  This is now an option to the ranef method for the
279            mer class.
280    
281            * src/cs_utils.c: Ensure that the nz component is -1 for a
282            compressed column-oriented matrix.  Minor formatting cleanup.
283

285            objects.
286

293    
294            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
295            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].
296    
297            * R/dtCMatrix.R, src/dtCMatrix.[ch] : CSparse-based solve methods
298            for the dtCMatrix class.

306    
307            * R/dgCMatrix.R: add  storage.mode(.) <- "double" for "matrix"
308            arguments, such that M %*% 1:6 now works
309            * Tests/matprod.R: test the above
310    
311    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>

320    
321            * R/dtCMatrix.R: allow coercion from  dgC* to triangular (dtC*)
322            * R/dsCMatrix.R: and symmetric (dsC*) 'Csparse' matrices.
323    
324            * R/Tsparse.R: Tsparse* -> Csparse* coercion now works and is tested in
325            * tests/simple: (extended)
326    
327            * R/sparseMatrix.R (isTriangular): now using much improved
328            * R/Auxiliaries.R (isTriC): new triangularity check for *CMatrix

331    
332            * src/dsyMatrix.c (dsyMatrix_as_dspMatrix): Propagate DimNames

343    
344            * R/lmer.R (resid and ranef methods):  Added methods for the
345            "residuals" and "resid" generic but only for linear mixed model
346            fits.  Changed the ranef method to return a list of data frames so
347            that the plot methods now work.
348

350    
351            * src/dpoMatrix.c (dpoMatrix_chol): Require n > 0 in call to
