6              generalize conversions between TsparseMatrix, CsparseMatrix,
7              denseMatrix and matrix.  Preserve triangularity property and
8              propagate Dimnames in the easy cases.

11    
12            * src/lmer.c: adjust checks in glmer_init for S4SXP
13            * tests/validObj.R: check of all(eq) should be all(eq@x) - worked
14            before S4SXP but for the wrong reasons.

16    2006-08-08  Douglas Bates  <bates@R-project.org>
17    
18            * src/Csparse.c (Csparse_crossprod): tcrossprod result has stype = -1.

25            R-level conversion to a sparse symmetric class.
26            * R/Tsparse.R,R/Csparse.R (crossprod and tcrossprod methods):
27            Remove conversion to sparse symmetric classes (now done in C code).

55            * DESCRIPTION (Version): 0.995-13 to be released to CRAN
56    
57            * DESCRIPTION (Lazydata): no, instead of 'yes' because it fails for:

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

108            allow subassignment for special sparse matrices.
109    
110            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
111

120

134            * tests/indexing.R: test it.
135    
136            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

152    
153    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
154    
155            * tests/simple.R: add check for correct dsT -> dgT coercion;
156                    add check for correct printing of symmetric sparse matrices.
157    
158            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
159            for sparse symmetric matrices.

179    
180            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
181                 ==> construction of illegal "*gTMatrix" via new() should
182                 now be much less easy:
183            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
184    
185            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
186                    directly.

225    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
226    
227            * R/dgTMatrix.R (colSums): etc. All four of
228            colSums(), rowSums(), colMeans(), rowMeans() now should work for
229            all "Matrices".
230

232    
233            * R/lmer.R (panel.ci): Add a reference line at zero and a
234            background grid to the qqmath plot of ranef.lmer.

236    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
237    
238            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
239            grouping factors to be specified in the formula as (1|foo/bar).
240

242    
243            * R/lmer.R (findbars and others): Change check of is.numeric to
244            !is.language to resolve the bug reported by Jacob Wegelin.
245    
246            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
247            code to evaluate inbreeding coefficients without calculating T,
248            based on code in Sargolzaei and Iwaisaki's paper.
249    
250    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
251    
252            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
253            generic and mer methods for isNested and denomDF. This denomDF was
254            an attempt to emulate that in lme but I don't think that makes
255            sense.  Use the trace of the hat matrix instead.
256    
257    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
258    
259            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

267            of lowerTriMatrix generic and methods to tril (also upper to triu)
268            and added a general band extractor.
269    
270    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
271    
272            * R/pedigree.R (pedigree): Replace sire and dam values outside the
273            allowable range with NAs. Added a corresponding check in the
274            validity check for the pedigree class.
275    
276            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
277            crossprod methods now inherits from symmetricMatrix.
278    
279    2006-05-15  Douglas Bates  <bates@stat.wisc.edu>
280    
281            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
282            generics lowerTriMatrix and upperTriMatrix along with methods for
283            the Csparse virtual class.  Also added a C function Csparse_band
284            that implements these methods by calling cholmod_band.
285    
286    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
287    
288            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
289            erased when it was NULL.  This led to invalid subselections!
290    
291    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
292    
293            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
294            in method for "t" so as not to lose the unit diagonal property.
295    
296    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
297    
298            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
299            and methods.  This is now an option to the ranef method for the
300            mer class.
301    
302            * src/cs_utils.c: Ensure that the nz component is -1 for a
303            compressed column-oriented matrix.  Minor formatting cleanup.
304    
305            * man/lmer-class.Rd: Document the qqmath method for ranef.lmer
306            objects.
307

309    
310            * R/Auxiliaries.R (diagU2N): new for the solve() methods in

312    
313    2006-04-15  Douglas Bates  <bates@stat.wisc.edu>
314    
315            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
316            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].

327    
328            * R/dgCMatrix.R: add  storage.mode(.) <- "double" for "matrix"
329            arguments, such that M %*% 1:6 now works
330            * Tests/matprod.R: test the above
331    
332    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>

341    
342            * R/dtCMatrix.R: allow coercion from  dgC* to triangular (dtC*)
343            * R/dsCMatrix.R: and symmetric (dsC*) 'Csparse' matrices.
344    
345            * R/Tsparse.R: Tsparse* -> Csparse* coercion now works and is tested in
346            * tests/simple: (extended)
347    
348            * R/sparseMatrix.R (isTriangular): now using much improved

352    
353            * src/dsyMatrix.c (dsyMatrix_as_dspMatrix): Propagate DimNames

364    
365            * R/lmer.R (resid and ranef methods):  Added methods for the
366            "residuals" and "resid" generic but only for linear mixed model
367            fits.  Changed the ranef method to return a list of data frames so
368            that the plot methods now work.
369
