59    
60            * src/lmer.c: adjust checks in glmer_init for S4SXP

156            allow subassignment for special sparse matrices.
157    
158            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
159    
160            * src/lmer.c (mer_MCMCsamp, glmer_MCMCsamp): new 'verbose'

168    
169            * R/Matrix.R("["): disable ("Matrix", i = "logical", j = "missing"),

182            * tests/indexing.R: test it.
183    
184            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

200    
201    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
202    
203            * tests/simple.R: add check for correct dsT -> dgT coercion;
204                    add check for correct printing of symmetric sparse matrices.
205    
206            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
207            for sparse symmetric matrices.

227    
228            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
229                 ==> construction of illegal "*gTMatrix" via new() should
230                 now be much less easy:
231            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
232    
233            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
234                    directly.

272    
273    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
274    
275            * R/dgTMatrix.R (colSums): etc. All four of
276            colSums(), rowSums(), colMeans(), rowMeans() now should work for
277            all "Matrices".
278

280    
281            * R/lmer.R (panel.ci): Add a reference line at zero and a
282            background grid to the qqmath plot of ranef.lmer.
283    
284    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
285    
286            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
287            grouping factors to be specified in the formula as (1|foo/bar).
288    
289    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
290    
291            * R/lmer.R (findbars and others): Change check of is.numeric to
292            !is.language to resolve the bug reported by Jacob Wegelin.
293    
294            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
295            code to evaluate inbreeding coefficients without calculating T,
296            based on code in Sargolzaei and Iwaisaki's paper.
297    
298    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
299    
300            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
301            generic and mer methods for isNested and denomDF. This denomDF was
302            an attempt to emulate that in lme but I don't think that makes
303            sense.  Use the trace of the hat matrix instead.
304    
305    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
306    
307            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

309            * src/dgTMatrix.c: ditto (also: src/init.c src/dgTMatrix.h)
310    
311    
312    2006-05-17  Douglas Bates  <bates@stat.wisc.edu>

314            *  R/{AllGeneric.R,Csparse.R},man/band.Rd,NAMESPACE: changed name
315            of lowerTriMatrix generic and methods to tril (also upper to triu)
316            and added a general band extractor.
317    
318    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
319    
320            * R/pedigree.R (pedigree): Replace sire and dam values outside the
321            allowable range with NAs. Added a corresponding check in the
322            validity check for the pedigree class.
323    
324            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
325            crossprod methods now inherits from symmetricMatrix.

327    2006-05-15  Douglas Bates  <bates@stat.wisc.edu>
328    
329            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
330            generics lowerTriMatrix and upperTriMatrix along with methods for
331            the Csparse virtual class.  Also added a C function Csparse_band
332            that implements these methods by calling cholmod_band.
333    
334    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
335    
336            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
337            erased when it was NULL.  This led to invalid subselections!
338    
339    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
340    
341            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
342            in method for "t" so as not to lose the unit diagonal property.
343    
344    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
345    
346            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
347            and methods.  This is now an option to the ranef method for the
348            mer class.
349    
350            * src/cs_utils.c: Ensure that the nz component is -1 for a
351            compressed column-oriented matrix.  Minor formatting cleanup.
352    
353            * man/lmer-class.Rd: Document the qqmath method for ranef.lmer
354            objects.
355    
356    2006-04-19  Martin Maechler  <maechler@stat.math.ethz.ch>
357    
358            * R/Auxiliaries.R (diagU2N): new for the solve() methods in
359            * R/dtCMatrix.R: where dgC -> dgT coercion now preserves diag = "U".
360    
361    2006-04-15  Douglas Bates  <bates@stat.wisc.edu>
362    
363            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
364            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].
365    
366            * R/dtCMatrix.R, src/dtCMatrix.[ch] : CSparse-based solve methods
367            for the dtCMatrix class.
