_D_e_s_c_r_i_p_t_i_o_n:

     View or manipulate the color palette which is used when a `col='
     has a numeric index.

_U_s_a_g_e:

     palette(value)

_A_r_g_u_m_e_n_t_s:

   value: an optional character vector.

_D_e_t_a_i_l_s:

     If `value' has length 1, it is taken to be the name of a built in
     color palette.  If `value' has length greater than 1 it is assumed
     to contain a description of the colors which are to make up the
     new palette (either by name or by RGB levels).

     If `value' is omitted or has length 0, no change is made the
     current palette.

     Currently, the only built-in palette is `"default"'.

_V_a_l_u_e:

     The palette which was in effect.  This is `invisible' unless the
     argument is omitted.

_S_e_e _A_l_s_o:

     `colors' for the vector of built-in ``named'' colors; `hsv',
     `gray', `rainbow', `terrain.colors',... to construct colors.

_E_x_a_m_p_l_e_s:

     palette()               # obtain the current palette
     palette(rainbow(6))     # six color rainbow

     (palette(gray(seq(0,.9,len=25)))) # gray scales; print old palette
     matplot(outer(1:100,1:30), type='l', lty=1,lwd=2, col=1:30,
             main = "Gray Scales Palette",
             sub = "palette(gray(seq(0,.9,len=25)))")
     palette("default")      # reset back to the default
