2    
3            * R/AllGeneric.R: add "qr" and "chol" generics; via 'trick' since
4            the base version has no "..." argument.
5    
6            * R/sparseMatrix.R (prSpMatrix): fix the triangular unit diagonal case.
7    
8            * R/Matrix.R: define and
9            * NAMESPACE: export as.numeric() and as.logical() methods.
10                    Let's hope these do not badly slow down something...
11            Finally export the zapsmall() method.
12    
13    2006-08-17  Douglas Bates  <bates@R-project.org>

44    
45            * src/lmer.c: adjust checks in glmer_init for S4SXP

141            allow subassignment for special sparse matrices.
142    
143            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
144    
145            * src/lmer.c (mer_MCMCsamp, glmer_MCMCsamp): new 'verbose'

153    
154            * R/Matrix.R("["): disable ("Matrix", i = "logical", j = "missing"),

167            * tests/indexing.R: test it.
168    
169            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

185    
186    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
187    
188            * tests/simple.R: add check for correct dsT -> dgT coercion;
189                    add check for correct printing of symmetric sparse matrices.
190    
191            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
192            for sparse symmetric matrices.

212    
213            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
214                 ==> construction of illegal "*gTMatrix" via new() should
215                 now be much less easy:
216            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
217    
218            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
219                    directly.
220            * man/Matrix.Rd: documents it.
221

257    
258    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
259    
260            * R/dgTMatrix.R (colSums): etc. All four of
261            colSums(), rowSums(), colMeans(), rowMeans() now should work for
262            all "Matrices".

265    
266            * R/lmer.R (panel.ci): Add a reference line at zero and a
267            background grid to the qqmath plot of ranef.lmer.
268    
269    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
270    
271            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
272            grouping factors to be specified in the formula as (1|foo/bar).
273

275    
276            * R/lmer.R (findbars and others): Change check of is.numeric to
277            !is.language to resolve the bug reported by Jacob Wegelin.
278    
279            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
280            code to evaluate inbreeding coefficients without calculating T,
281            based on code in Sargolzaei and Iwaisaki's paper.
282    
283    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>
284    
285            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
286            generic and mer methods for isNested and denomDF. This denomDF was
287            an attempt to emulate that in lme but I don't think that makes
288            sense.  Use the trace of the hat matrix instead.
289    
290    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
291    
292            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

294            * src/dgTMatrix.c: ditto (also: src/init.c src/dgTMatrix.h)
295    
296

299            *  R/{AllGeneric.R,Csparse.R},man/band.Rd,NAMESPACE: changed name
300            of lowerTriMatrix generic and methods to tril (also upper to triu)

303    2006-05-16  Douglas Bates  <bates@stat.wisc.edu>
304    
305            * R/pedigree.R (pedigree): Replace sire and dam values outside the
306            allowable range with NAs. Added a corresponding check in the
307            validity check for the pedigree class.
308    
309            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
310            crossprod methods now inherits from symmetricMatrix.

313    
314            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
315            generics lowerTriMatrix and upperTriMatrix along with methods for
316            the Csparse virtual class.  Also added a C function Csparse_band
317            that implements these methods by calling cholmod_band.
318    
319    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
320    
321            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
322            erased when it was NULL.  This led to invalid subselections!
323    
324    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
325    
326            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
327            in method for "t" so as not to lose the unit diagonal property.
328    
329    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
330    
331            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
332            and methods.  This is now an option to the ranef method for the
333            mer class.
334    
335            * src/cs_utils.c: Ensure that the nz component is -1 for a
336            compressed column-oriented matrix.  Minor formatting cleanup.
337

339            objects.
340    
341    2006-04-19  Martin Maechler  <maechler@stat.math.ethz.ch>
342    
343            * R/Auxiliaries.R (diagU2N): new for the solve() methods in
344            * R/dtCMatrix.R: where dgC -> dgT coercion now preserves diag = "U".
345    
346    2006-04-15  Douglas Bates  <bates@stat.wisc.edu>
347    
348            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library
349            in cs.[ch] and utilities to interface to that code in cs_utils.[ch].
350    
351            * R/dtCMatrix.R, src/dtCMatrix.[ch] : CSparse-based solve methods
352            for the dtCMatrix class.

360    
361            * R/dgCMatrix.R: add  storage.mode(.) <- "double" for "matrix"
362            arguments, such that M %*% 1:6 now works
363            * Tests/matprod.R: test the above
364    
365    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>
366    
367            * R/lmer.R (qqmath,ranef.lmer-method): added a qqmath method for
368            the ranef.lmer class.
