_D_e_s_c_r_i_p_t_i_o_n:

     Finds the objects in a package which are undocumented, in the
     sense that they are visible to the user (or data objects or S4
     classes provided by the package), but no documentation entry
     exists.

_U_s_a_g_e:

     undoc(package, dir, lib.loc = NULL)

_A_r_g_u_m_e_n_t_s:

 package: a character string naming an installed package.

     dir: a character string specifying the path to a package's root
          source directory.  This must contain the subdirectory 'man'
          with R documentation sources (in Rd format), and at least one
          of the 'R' or 'data' subdirectories with R code or data
          objects, respectively.

 lib.loc: a character vector of directory names of R libraries, or
          'NULL'.  The default value of 'NULL' corresponds to all
          libraries currently known.  The specified library trees are
          used to search for 'package'.

_D_e_t_a_i_l_s:

     This function is useful for package maintainers mostly.  In
     principle, _all_ user-level R objects should be documented.

     The 'base' package is special as it contains the primitives and
     these do not have definitions available at code level.  We provide
     equivalent closures in environments '.ArgsEnv' and
     '.GenericArgsEnv' in the 'base' package that are used for various
     purposes: 'undoc("base")' checks that all the primitives that are
     not language constructs are prototyped in those environments and
     no others are.

_V_a_l_u_e:

     An object of class '"undoc"' which is a list of character vectors
     containing the names of the undocumented objects split according
     to documentation type.  This representation is still experimental,
     and might change in future versions.

     There is a 'print' method for nicely displaying the information
     contained in such objects.

_S_e_e _A_l_s_o:

     'codoc', 'QC'

_E_x_a_m_p_l_e_s:

     undoc("tools")                  # Undocumented objects in 'tools'
