backsolve... --> class()es for special matrices ?
...().. Well, we (R core) have discussed matrix classes months and years ago.. and haven't really started doing anything about it. I think we then agreed to follow Splus' Matrix library and use class "Matrix" (and classes inheriting from "Matrix", i.e. class == c("specialMatrix", "Matrix") ). If we really go into this, then we'd probably want to use the SAME class names that S-plus' library(Matrix) is using. Also, I remember that people (on the old R-testers list?) very much desired to have 1-column or 1-row matrices instead of vectors when work...
