_F_o_r_m_a_t:

     A data frame with 100 observations on the following 2 variables.

     _a_g_e age

     _l_e_n_g_t_h a numeric vector

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

     This data is simulated from values reported in a paper by Porch,
     Wilson and Nieland titled "A new growth model for red drum
     (Sciaenops ocellaus) that accommodates seasonal and ontogenic
     changes in growth rates" which appeard in _Fishery Bulletin_
     100(1) (<URL: http://fishbull.noaa.gov/1001/por.pdf>). They
     attribute the data to Beckman et. al and say it comes from
     measurements in the Northern Gulf of Mexico, between September
     1985 and October 1998.
