A lot longer than rowSums ...

This made me smile. The rowsums function was originally an internal
part of the survival package, used for fast computation of certain sums
when there is a cluster() statement. It was Statistical Sciences
(S-Plus) who moved it to global status. That is, they used it in enough
other places that they decided to speed it up, took over the
maintainance and ownership of the function (with my blessing), and
ceased to label it as part of "survival" in the manual.
This "metabug" can't be laid at R's feet.
