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

     This function displays a star coordinates plot introduced by
     Kondogan (2001).

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

     starcoord(data, main = NULL, class = FALSE, outliers, vars = 0, 
     scale = 1, cex = 0.8, lwd = 0.25, lty = par("lty"))

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

    data: The dataset

    main: The title of the plot 

   class: The class 

outliers: instances to be highlighted as potential outliers 

    vars: variable to be scaled

   scale: The scale factor

     cex: A numerical value giving the amount by which plotting text
          and symbols should be scaled. 

     lwd: the width of the lines representing the axis

     lty: The type of the lines representing the axis

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

     This plot is not recommended for a large number of features (say
     more than 50)

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

     Returns a star coordinates plot of the data matrix
