500    
501            * R/dgCMatrix.R: aargh: "Arith(<dgC>, numeric)" was wrong because

737            allow subassignment for special sparse matrices.
738    
739            * R/Auxiliaries.R (as_geClass): factor out the  .M.kind() functionality
740    
741            * src/lmer.c (mer_MCMCsamp, glmer_MCMCsamp): new 'verbose'
742            argument; in glmer_*(): print only if(verbose).

745    
746            * src/lmer.h, src/init.h, R/lmer.R:  related to above.

749    
750            * R/Matrix.R("["): disable ("Matrix", i = "logical", j = "missing"),
751                    since that wrongly triggers also for M[ logi , ]

763            * tests/indexing.R: test it.
764    
765            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;
766            * man/isSymmetric-methods.Rd: and document it.
767    
768            * R/SparseM-conv.R: added coercion methods for some 'SparseM' matrices.

781    
782    2006-07-15  Martin Maechler  <maechler@stat.math.ethz.ch>
783    
784            * tests/simple.R: add check for correct dsT -> dgT coercion;
785                    add check for correct printing of symmetric sparse matrices.
786    
787            * R/Auxiliaries.R (non0ind): return *all* non-0 entry indices also
788            for sparse symmetric matrices.

811                 now be much less easy:
812            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
813    
814            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
815                    directly.
816            * man/Matrix.Rd: documents it.
817

853    
854    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
855    
856            * R/dgTMatrix.R (colSums): etc. All four of
857            colSums(), rowSums(), colMeans(), rowMeans() now should work for
858            all "Matrices".
859    
860    2006-06-01  Douglas Bates  <bates@stat.wisc.edu>
861    
862            * R/lmer.R (panel.ci): Add a reference line at zero and a
863            background grid to the qqmath plot of ranef.lmer.
864    
865    2006-05-30  Douglas Bates  <bates@stat.wisc.edu>
866    
867            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested
868            grouping factors to be specified in the formula as (1|foo/bar).
869

871    
872            * R/lmer.R (findbars and others): Change check of is.numeric to
873            !is.language to resolve the bug reported by Jacob Wegelin.
874    
875            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
876            code to evaluate inbreeding coefficients without calculating T,
877            based on code in Sargolzaei and Iwaisaki's paper.

880    
881            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
882            generic and mer methods for isNested and denomDF. This denomDF was
883            an attempt to emulate that in lme but I don't think that makes
884            sense.  Use the trace of the hat matrix instead.
885    
886    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
887    
888            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

900    
901            * R/pedigree.R (pedigree): Replace sire and dam values outside the
902            allowable range with NAs. Added a corresponding check in the
903            validity check for the pedigree class.
904    
905            * R/[CT]sparse.R ([t]crossprod): The result of single-argument

909    
910            * R/AllGeneric.R (lowerTriMatrix): Added (but did not export)
911            generics lowerTriMatrix and upperTriMatrix along with methods for
912            the Csparse virtual class.  Also added a C function Csparse_band
913            that implements these methods by calling cholmod_band.
914    
915    2006-05-15  Martin Maechler  <maechler@stat.math.ethz.ch>
916    
917            * R/Tsparse.R ("["): column or row subsetting; @Dimnames[k] got
918            erased when it was NULL.  This led to invalid subselections!
919    
920    2006-04-25  Douglas Bates  <bates@stat.wisc.edu>
921    
922            * R/dtCMatrix.R: avoid coercion of dtCMatrix object to dgCMatrix
923            in method for "t" so as not to lose the unit diagonal property.
924    
925    2006-04-19  Douglas Bates  <bates@stat.wisc.edu>
926    
927            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
928            and methods.  This is now an option to the ranef method for the
929            mer class.
930    
931            * src/cs_utils.c: Ensure that the nz component is -1 for a
932            compressed column-oriented matrix.  Minor formatting cleanup.
933

943    
944            * src/cs.[ch],src/cs_utils.[ch] : Added Tim Davis' CSparse library

960    
961    2006-04-03  Douglas Bates  <bates@stat.wisc.edu>

970    
971            * R/dtCMatrix.R: allow coercion from  dgC* to triangular (dtC*)
972            * R/dsCMatrix.R: and symmetric (dsC*) 'Csparse' matrices.
973    
974            * R/Tsparse.R: Tsparse* -> Csparse* coercion now works and is tested in
975            * tests/simple: (extended)
976    
977            * R/sparseMatrix.R (isTriangular): now using much improved
978            * R/Auxiliaries.R (isTriC): new triangularity check for *CMatrix

993    
994            * R/lmer.R (resid and ranef methods):  Added methods for the
995            "residuals" and "resid" generic but only for linear mixed model
996            fits.  Changed the ranef method to return a list of data frames so
997            that the plot methods now work.
998

1000    
1001            * src/dpoMatrix.c (dpoMatrix_chol): Require n > 0 in call to
