Hi

few typos i've found

\link{Encoding}

writing R extensions, pag 73 (pdf version), note 1, 

and we provided an emulation on Windows 2000): see ?dyn.oad
                                            ^          ^^

R Installation and Administration

A patched version of the current release, `r-patched' and the current
                                                    ^^

I also would like to close bug/wishlist #9613 ... It was a
juvenile mistake!  :)


Thank you,
