     Obtain the chromosome lengths in a 'cross' or 'map' object.

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

     chrlen(object)

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

  object: An object of class 'map' or of class 'cross'.

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

     Returns a vector of chromosome lengths.  If the cross has
     sex-specific maps, it returns a 2-row matrix with the two lengths
     for each chromosome.
