_s_p_i_n_3_R

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

     Simple spin function to rotate and to inspect  a 3-dimensional
     cloud of points

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

       spin3R(x, alpha = 1, delay = 0.015, na.rm=FALSE)

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

       x: '(nx3)'-matrix of points 

   alpha: angle between successive projections 

   delay: delay in seconds between two plots 

   na.rm: if TRUE 'NA' values are removed otherwise exchanged by mean

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

     'spin3R' computes two-dimensional projections  of '(nx3)'-matrix
     'x' and plots them on the graphics devise. The cloud of points is
     rotated step by step. The rotation is defined by a tcl/tk control 
     widget. 'spin3R' requires tcl/tk package of R.

_N_o_t_e:

     version 01/2003

_A_u_t_h_o_r(_s):

     Statistics. Wadsworth & Brooks/Cole, Belmont, California.

_S_e_e _A_l_s_o:

     'spin' of S-Plus

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

       xyz<-matrix(rnorm(300),100,3)
       # now start:     spin3R(xyz)
