     The data set 'metalcut' is an attempt to determine which cutting
     method (vertical or horizontal) yields the quickest and smoothest
     cuts for three types of metal stock (angle, flat, round). Students
     from the Biological Engineering Department measured cutting times
     and quality for the six combinations of method and stock.

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

     A data frame with 18 observations on the following 4 variables.

     _c_u_t : cutting method (hcut for horizontal or vcut for vertical

     _s_t_o_c_k : type of metal stock (angle, flat or round)

     _t_i_m_e : cutting time (in seconds)

     _q_u_a_l_i_t_y : smooth (0) or rough (1)
