_D_e_s_c_r_i_p_t_i_o_n:

     Display a smooth density estimate.

_U_s_a_g_e:

     ggdensity(plot = .PLOT, aesthetics=list(), ..., data=NULL)

_A_r_g_u_m_e_n_t_s:

    plot: the plot object to modify

aesthetics: named list of aesthetic mappings, see details for more
          information

     ...: other options, see details for more information

    data: data source, if not specified the plot default will be used

_D_e_t_a_i_l_s:

     Aesthetic mappings that this grob function understands:

        *  'x':x position (required)

        *  'weight': observation weights

     These can be specified in the plot defaults (see 'ggplot') or in
     the 'aesthetics' argument.  If you want to modify the position of
     the points or any axis options, you will need to add a position
     scale to the plot.  These functions start with 'ps', eg.
     'pscontinuous' or 'pscategorical'

     Other options:

        *  'adjust': see 'density' for details

        *  'kernel': kernel used for density estimation, see 'density'
           for details

        *  other aesthetic properties passed on to 'ggline'

        *  'weight': observation weights
