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

     Extract or replace the detector type.

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

     detector(object, ...)
     detector(object) <- value

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

  object: object with 'detector' attribute e.g. 'traps' 

   value: character string for detector type 

     ...: other arguments (not used) 

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

     Valid detector types in version 1.3 are 'single', 'multi',
     'proximity',  'count', 'quadratbinary', 'quadratcount' and
     'signal'. The detector type is  stored as an attribute of a
     'traps' object.  Detector types are  mostly described by Efford et
     al. (2009a,b).

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

     character string for detector type
