764            * R/diagMatrix.R (setAs): define coercion methods to sparse matrix
765            classes.
766            * R/sparseMatrix.R etc: multiplication of diagonal and sparse
767    
768    2006-06-08  Martin Maechler  <maechler@stat.math.ethz.ch>
769    
770            * R/dgTMatrix.R (colSums): etc. All four of
771            colSums(), rowSums(), colMeans(), rowMeans() now should work for
772            all "Matrices".
773    
774    2006-06-01  Douglas Bates  <bates@stat.wisc.edu>
775

782            grouping factors to be specified in the formula as (1|foo/bar).
783

795            * R/{lmer.R,AllGeneric.R}, src/{init.c,lmer.[ch]}: Added local
796            generic and mer methods for isNested and denomDF. This denomDF was
797            an attempt to emulate that in lme but I don't think that makes
798            sense.  Use the trace of the hat matrix instead.
799

840    
841            * R/lmer.R, R/AllGeneric.R, NAMESPACE: Remove the postVar generic
