It's the only correct form. And of course it finds the desired file:

   R> file.path(R.home('doc'), 'html', 'logo.jpg')
   [1] "/usr/share/R/doc/html/logo.jpg"
   R> 

because it knows about

   R> Sys.getenv("R_SHARE_DIR")
   [1] "/usr/share/R/share"
   R>

because, as Inaki reminded everyone, most distro had non-architecture
dependent files below /usr/share for years.
