_D_e_s_c_r_i_p_t_i_o_n:

     The inputs of the cassini problem are uniformly distributed on a
     '2'-dimensional space within 3 structures. The 2 external
     structures (classes) are banana-shaped structures and in between
     them, the middle structure (class) is a circle.

_U_s_a_g_e:

     mlbench.cassini(n, relsize=c(2,2,1))

_A_r_g_u_m_e_n_t_s:

       n: number of patterns to create

 relsize: relative size of the classes (vector of length 3)

_V_a_l_u_e:

     Returns an object of class '"mlbench.cassini"'  with components 

       x: input values

 classes: vector of length 'n' with target classes

_A_u_t_h_o_r(_s):

     Evgenia Dimitriadou and Andreas Weingessel

_E_x_a_m_p_l_e_s:

     p <- mlbench.cassini(5000)
     plot(p)
