175    
176            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
177

186    
187            * R/Matrix.R("["): disable ("Matrix", i = "logical", j = "missing"),

200            * tests/indexing.R: test it.
201    
202            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

218    
219    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
220    
221            * tests/simple.R: add check for correct dsT -> dgT coercion;
222                    add check for correct printing of symmetric sparse matrices.
223    
224            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
225            for sparse symmetric matrices.
226

245    
246            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
247                 ==> construction of illegal "*gTMatrix" via new() should

249            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
250    
251            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
252                    directly.

286    
287            * R/diagMatrix.R (setAs): define coercion methods to sparse matrix
288            classes.
289            * R/sparseMatrix.R etc: multiplication of diagonal and sparse
290    
291    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
292    
293            * R/dgTMatrix.R (colSums): etc. All four of
294            colSums(), rowSums(), colMeans(), rowMeans() now should work for
295            all "Matrices".
296

298    
299            * R/lmer.R (panel.ci): Add a reference line at zero and a
300            background grid to the qqmath plot of ranef.lmer.
301    
302    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
303    
304            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
305            grouping factors to be specified in the formula as (1|foo/bar).
306    
307    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
308    
309            * R/lmer.R (findbars and others): Change check of is.numeric to
310            !is.language to resolve the bug reported by Jacob Wegelin.
311    
312            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
313            code to evaluate inbreeding coefficients without calculating T,
314            based on code in Sargolzaei and Iwaisaki's paper.
315    
316    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
317    
318            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
319            generic and mer methods for isNested and denomDF. This denomDF was
320            an attempt to emulate that in lme but I don't think that makes
321            sense.  Use the trace of the hat matrix instead.
322    
323    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
324    
325            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use
326            the C code depending on a slot structure that's no longer valid.
327            * src/dgTMatrix.c: ditto (also: src/init.c src/dgTMatrix.h)
328    
329    
330    2006-05-17  Douglas Bates  <bates@stat.wisc.edu>
331    
332            *  R/{AllGeneric.R,Csparse.R},man/band.Rd,NAMESPACE: changed name
333            of lowerTriMatrix generic and methods to tril (also upper to triu)
334            and added a general band extractor.
335    
336    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
337    
338            * R/pedigree.R (pedigree): Replace sire and dam values outside the
339            allowable range with NAs. Added a corresponding check in the
340            validity check for the pedigree class.
341    
342            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
343            crossprod methods now inherits from symmetricMatrix.
344    
345    2006-05-15  Douglas Bates  <bates@stat.wisc.edu>
346    
347            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
348            generics lowerTriMatrix and upperTriMatrix along with methods for
349            the Csparse virtual class.  Also added a C function Csparse_band
350            that implements these methods by calling cholmod_band.
351    
352    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
353    
354            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
355            erased when it was NULL.  This led to invalid subselections!
356    
357    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
358    
359            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
360            in method for "t" so as not to lose the unit diagonal property.
361    
362    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
363    
364            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
365            and methods.  This is now an option to the ranef method for the
366            mer class.
367    
368            * src/cs_utils.c: Ensure that the nz component is -1 for a
