     an 'image' plot.

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

       metre(xl, yb, xr, yt, lab, cols = risk.colors(length(lab) - 1), 
             shift = 0, cex = 1)

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

xl,yb,xr,yt: 'x,y' coordinates of the left-bottom and right-top corners
          of the color level metre bar.

     lab: metre level labels in the metre.

    cols: associated colours, defaults to use 'risk.colors'.

   shift: distance to shift the label texts away from the metre bar.

     cex: numeric character expansion factor.
