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

     Calculation of benchmark doses based on continuous or qunatal
     dose-response data.

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

     bmd(object, level, def = c("excess", "additional"), interval = c("delta"))

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

  object: object of class 'drc'

   level: numeric vector of response levels for which to calculate
          benchmark doses

     def: character string specifiying the definition of benchmark dose
          to use

interval: character string specifying the type of confidence interval
          to use

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

     This package project just started and is still under development.
     The aim to provide an R package  calculating the benchmark dose
     (BMD) and the lower limit of the corresponding 95% confidence
     interval (BMDL) for continuous and quantal dose-response data for
     a range of dose-response model based on the available definitions
     of the benchmark dose concepts.

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

     A matrix with two column, one containing BMD and the other
     containing BMDL.
