3            * R/Matrix.R (Matrix): has become much "smarter" now auto-producing
4                    many different kinds of matrices.
5            * R/*.R: quite a few new methods were needed for R CMD check with
6                    new Matrix().  Very good for users playing around.

133                    Logical and character indexing now work too.
134            * R/Matrix.R: cheap "[<-" methods for denseMatrix now work
135            * tests/indexing.R: new, including *.Rout.save

139    
140          * src/dgTMatrix.c (graphNEL_as_dgTMatrix): Corrected the position          * src/dgTMatrix.c (graphNEL_as_dgTMatrix): Corrected the position
