3            * inst/include/Matrix_stubs.c,Matrix.h: Add declarations and stubs
4            for exported functions
5            * src/Makefile, src/CHOLMOD/Lib/Makefile, src/Metis,CAMD,CCOLAMD:
6            Remove partitioning algorithms for sparse matrix reordering.  The

8            rarely used.
9            * src/triplet_to_col.[ch],MMHB.[ch]: Remove triplet_to_col.  Such
10            operations are now done entirely in CHOLMOD code.

358            * R/lgCMatrix.R (diag): for new method
359    
360            * R/AllClass.R (TsparseMatrix): do use Tsparse_validate
361                 ==> construction of illegal "*gTMatrix" via new() should
362                 now be much less easy:
363            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
364    
365            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
366                    directly.
367            * man/Matrix.Rd: documents it.
368    
369    2006-07-06  Douglas Bates  <bates@R-project.org>
370    
371            * src/pedigree.c (pedigree_inbreeding): Correction in
372            initialization.  This function is not currently being used and is
373            not fully tested.
374    
375            * NAMESPACE, R/{AllClass.R,lmer.R}, src/{init.c,lmer.c}:
376            Introduced the glmer class.  Added code for mcmcmsamp on glmer
377            objects.  Modified validity check on pedigree objects to account
378            for nonparallel patterns of missingness of parents.

400    
401            * R/diagMatrix.R (setAs): define coercion methods to sparse matrix
402            classes.
403            * R/sparseMatrix.R etc: multiplication of diagonal and sparse
404    
405    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
406    
407            * R/dgTMatrix.R (colSums): etc. All four of
408            colSums(), rowSums(), colMeans(), rowMeans() now should work for
409            all "Matrices".
410    
411    2006-06-01  Douglas Bates  <bates@stat.wisc.edu>
412    
413            * R/lmer.R (panel.ci): Add a reference line at zero and a
414            background grid to the qqmath plot of ranef.lmer.
415    
416    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
417    
418            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
419            grouping factors to be specified in the formula as (1|foo/bar).
420

422    
423            * R/lmer.R (findbars and others): Change check of is.numeric to
424            !is.language to resolve the bug reported by Jacob Wegelin.
425    
426            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
427            code to evaluate inbreeding coefficients without calculating T,

432            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
433            generic and mer methods for isNested and denomDF. This denomDF was
434            an attempt to emulate that in lme but I don't think that makes
435            sense.  Use the trace of the hat matrix instead.
436    
437    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
438

451    
452            * R/pedigree.R (pedigree): Replace sire and dam values outside the
453            allowable range with NAs. Added a corresponding check in the

462            generics lowerTriMatrix and upperTriMatrix along with methods for
463            the Csparse virtual class.  Also added a C function Csparse_band
464            that implements these methods by calling cholmod_band.
465

467    
468            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
469            erased when it was NULL.  This led to invalid subselections!
470    
471    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
472    
473            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
474            in method for "t" so as not to lose the unit diagonal property.
475    
476    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
477    
478            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
479            and methods.  This is now an option to the ranef method for the
480            mer class.
