Hi all,
As you know, spplot function of sp package is very powerful and even allows to
superimpose contour lines with the option 'contour=TRUE'. The color of the
contour line can be changed with the 'col' option. I'd like to know if it
possible to improve on this:
1) changing the color of the contour line to more than one color, based on the
values of the spplot variable (for example, a scale of blue colors).
2) if option 1) is possible, is it possible to fill the areas between two
nearby color lines with a color equal to the color line? (As for function
filled.contour(), but inside the spplot).
Thanks!!!
Nicola
