_D_e_s_c_r_i_p_t_i_o_n:

     Interact with the user to choose the package repositories to be
     used.

_U_s_a_g_e:

     setRepositories(graphics = getOption("menu.graphics"), ind = NULL)

_A_r_g_u_m_e_n_t_s:

graphics: Logical. If true and 'tcltk' and an X server are available,
          use a Tk widget, or if under the AQUA interface use a Mac OS
          X widget, otherwise use a text list in the console.

     ind: 'NULL' or a vector of integer indices, which have the same
          effect as if they were entered at the prompt for
          'graphics=FALSE'.

_D_e_t_a_i_l_s:

     The default list of known repositories is stored in the file
     'R_HOME/etc/repositories'. That file can be edited for a site, or
     a user can have a personal copy in 'HOME/.R/repositories' which
     will take precedence.

     The items that are preselected are those that are currently in
     'options("repos")' plus those marked as default in the list of
     known repositories.

     This function requires the R session to be interactive unless
     'ind' is supplied.

_V_a_l_u_e:

     This function is invoked mainly for its side effect of updating
     'options("repos")'.  It returns (invisibly) the previous 'repos'
     options setting (as a 'list' with component 'repos') or 'NULL' if
     no changes were applied.

_S_e_e _A_l_s_o:

     'chooseCRANmirror', 'install.packages'.
