[R] Contour Plots

[mhoward]

r-help,

 I can't seem to get the below data organized in such a manner so as to
generate a contour plot
using any of the functions {lattice.contourplot, base.contour,
base.filled.contour}. I was wondering
if anyone could please tell me what I need to do to accomplish this.
