141    
142            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
143            order to match the generic (and evade .local(..)).

204    
205            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
206            coercion to "nMatrix" and "pMatrix"
207
