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

     The 'warping' data frame has 8 rows and 5 columns.

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

     data(warping)

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

     This data frame contains the following columns:

     _t_e_m_p_e_r_a_t_u_r_e a numeric vector with temperature (degrees
          centrigrade)

     _C_u_4_0 a numeric vector with extent of warping with Cu content 40%

     _C_u_6_0 a numeric vector with extent of warping with Cu content 60%

     _C_u_8_0 a numeric vector with extent of warping with Cu content 80%

     _C_u_1_0_0 a numeric vector with extent of warping with Cu content 100%

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

     These data are from a factorial experiment to investigate how
     metal plates with different levels of copper content warp when
     subjected to different temperatures. Warping is undesirable.

_E_x_a_m_p_l_e_s:

     data(warping)
     matplot(x=warping[,1], y=warping[,-1], ty="l", xlab="Temperature", ylab="warping")
     legend(50, 15, c("40%", "60%", "80%", "100%"), lty=1:4, col=1:4)
