1    2006-03-06  Martin Maechler  <maechler@stat.math.ethz.ch>
2    
3            * R/AllClass.R: define "summary.mer" and "*.lmer"
4            * R/lmer.R (summary): summary(<mer>) computes & returns the above;
5            * R/lmer.R (show): now works with summary()
6    
7    2006-03-04  Martin Maechler  <maechler@stat.math.ethz.ch>
8    
9            * R/dgCMatrix.R: finally direct "Arith"  dgC o dgC
10            * R/Auxiliaries.R (WhichintersectInd): and other utilities to
11                    support the above
12    
13    2006-02-07  Douglas Bates  <bates@stat.wisc.edu>
14    
15            * R/lmer.R (lmer): fix initial values of offset and weights for glm.fit.
16            Use glmFit$prior.weights for weights in a glmm.
17            Allow an option usePQL = FALSE to skip the PQL steps for the
18            Laplace method (and, in time, the AGQ method).
19    
20            * src/lmer.c (mer_factor): Move downdating and factoring of XtX
21            into a separate function internal_mer_Xfactor to be able to call
22            it from internal_bhat.
23    
24    2006-01-23  Martin Maechler  <maechler@stat.math.ethz.ch>
25    
26            * tests/Class+Meth.R (tstMatrixClass): function for much better
27            testing; now again of all actual classes.
28    
29            * src/Mutils.c (MAKE_TRIANGULAR_BODY, MAKE_SYMMETRIC_BODY):
30                    use macros and define make_d_matrix_* and make_i_matrix_*
31                    where _i_ is for the ldense routines:
32    
33            * src/ldense.c (ltrMatrix_as_lgeMatrix): provide functions
34            * src/ldense.c (lsyMatrix_as_lgeMatrix):
35    
36            * R/ldenseMatrix.R: use the above in setAs(*,"lgeMatrix")
37    
38    
39    2006-01-16  Martin Maechler  <maechler@stat.math.ethz.ch>
40    
41            * R/Matrix.R (Matrix): has become much "smarter" now auto-producing
42                    many different kinds of matrices.
43            * R/*.R: quite a few new methods were needed for R CMD check with
44                    new Matrix().  Very good for users playing around.
45    
46
