200

214            * tests/indexing.R: test it.
215    
216            * NAMESPACE: export isSymmetric(); has been a generic in "base" for a while;

263            * tests/Class+Meth.R: assertError() for some illegal "dgT*"
264    
265            * R/Matrix.R (Matrix): Matrix(0, nrow,ncol) now "goes sparse"
266                    directly.

305    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
306    
307            * R/dgTMatrix.R (colSums): etc. All four of
308            colSums(), rowSums(), colMeans(), rowMeans() now should work for

312

317    
318            * R/lmer.R (expandSlash): Functions (non-exported) to allow nested

322    
323            * R/lmer.R (findbars and others): Change check of is.numeric to
324            !is.language to resolve the bug reported by Jacob Wegelin.
325    
326            * src/pedigree.c (pedigree_inbreeding): Initial implementation of
327            code to evaluate inbreeding coefficients without calculating T,
328            based on code in Sargolzaei and Iwaisaki's paper.
329    
330    2006-05-27  Douglas Bates  <bates@stat.wisc.edu>

332            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
333            generic and mer methods for isNested and denomDF. This denomDF was
334            an attempt to emulate that in lme but I don't think that makes
335            sense.  Use the trace of the hat matrix instead.
336    
337    2006-05-17  Martin Maechler  <maechler@stat.math.ethz.ch>
338    
339            * R/sparseMatrix.R: Matrix <-> graph methods: can no longer use

351    
352            * R/pedigree.R (pedigree): Replace sire and dam values outside the
353            allowable range with NAs. Added a corresponding check in the
354            validity check for the pedigree class.
355    
356            * R/[CT]sparse.R ([t]crossprod): The result of single-argument
357            crossprod methods now inherits from symmetricMatrix.
