10    
11            * R/AllGeneric.R: add "qr" and "chol" generics; via 'trick' since

15

18                    Let's hope these do not badly slow down something...

52    
53            * src/lmer.c: adjust checks in glmer_init for S4SXP

149            allow subassignment for special sparse matrices.
150    
151            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
152    
153            * src/lmer.c (mer_MCMCsamp, glmer_MCMCsamp): new 'verbose'

161    
162            * R/Matrix.R("["): disable ("Matrix", i = "logical", j = "missing"),

175            * tests/indexing.R: test it.
176    
177            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

193    
194    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
195    
196            * tests/simple.R: add check for correct dsT -> dgT coercion;
197                    add check for correct printing of symmetric sparse matrices.
198    
199            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
200            for sparse symmetric matrices.

220    
221            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
222                 ==> construction of illegal "*gTMatrix" via new() should
223                 now be much less easy:
224            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
225    
226            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
227                    directly.
228            * man/Matrix.Rd: documents it.
229

265    
266    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
267    
268            * R/dgTMatrix.R (colSums): etc. All four of
269            colSums(), rowSums(), colMeans(), rowMeans() now should work for
270            all "Matrices".
271

273    
274            * R/lmer.R (panel.ci): Add a reference line at zero and a
275            background grid to the qqmath plot of ranef.lmer.
276    
277    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
278    
279            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
280            grouping factors to be specified in the formula as (1|foo/bar).
281    
282    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
283    
284            * R/lmer.R (findbars and others): Change check of is.numeric to
285            !is.language to resolve the bug reported by Jacob Wegelin.
286    
287            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
288            code to evaluate inbreeding coefficients without calculating T,
289            based on code in Sargolzaei and Iwaisaki's paper.
290    
291    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
292    
293            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
294            generic and mer methods for isNested and denomDF. This denomDF was
295            an attempt to emulate that in lme but I don't think that makes
296            sense.  Use the trace of the hat matrix instead.
297    
298    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
299    
300            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

302            * src/dgTMatrix.c: ditto (also: src/init.c src/dgTMatrix.h)
303    
304

310    
311    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
312    
313            * R/pedigree.R (pedigree): Replace sire and dam values outside the
314            allowable range with NAs. Added a corresponding check in the
315            validity check for the pedigree class.
316    
317            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
318            crossprod methods now inherits from symmetricMatrix.

321    
322            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
323            generics lowerTriMatrix and upperTriMatrix along with methods for
324            the Csparse virtual class.  Also added a C function Csparse_band
325            that implements these methods by calling cholmod_band.
326    
327    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
328    
329            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
330            erased when it was NULL.  This led to invalid subselections!
331    
332    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
333    
334            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
335            in method for "t" so as not to lose the unit diagonal property.
336    
337    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
338    
339            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
340            and methods.  This is now an option to the ranef method for the
341            mer class.
342    
343            * src/cs_utils.c: Ensure that the nz component is -1 for a
344            compressed column-oriented matrix.  Minor formatting cleanup.
345

347            objects.
348    
349    2006-04-19  Martin Maechler  <maechler@stat.math.ethz.ch>
350    
351            * R/Auxiliaries.R (diagU2N): new for the solve() methods in
352            * R/dtCMatrix.R: where dgC -> dgT coercion now preserves diag = "U".
353    
354    2006-04-15  Douglas Bates  <bates@stat.wisc.edu>
355    
356            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
357            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].
358    
359            * R/dtCMatrix.R, src/dtCMatrix.[ch] : CSparse-based solve methods
360            for the dtCMatrix class.
