     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)
