_D_e_s_c_r_i_p_t_i_o_n:

     computes the poverty of an (income) vector according to the
     specified poverty measure

_U_s_a_g_e:

     pov(x, k, parameter = NULL,type = c("Watts", "Sen", "Foster"))

     Watts(x,k)
     Sen(x,k)
     Foster(x,k,parameter=1)

_A_r_g_u_m_e_n_t_s:

       x: a vector containing at least non-negative elements

       k: a constant giving the absolute poverty boundary

parameter: parameter of the poverty measure (if set to 'NULL' the
          default parameter of the respective measure is used)

    type: character string giving the measure used to compute poverty
          coefficient must be one of the strings in the default
          argument (the first character is sufficient). defaults to
          "Watts".

_D_e_t_a_i_l_s:

     'pov' is just a wrapper for the poverty measures of 'Watts', 'Sen'
     and 'Foster' (Foster / Greer / Thorbecke). If parameter is set to
     'NULL' the default from the respective function is used.

     'Foster' gives for parameter 1 the head count ratio and for
     parameter 2 the poverty gap ratio.

_V_a_l_u_e:

     the value of the poverty measure

_A_u_t_h_o_r(_s):
