Thiago,
This will not be simple using filled.contour, as this changes the layout from
the figure.
You might try the function image2D from plot3D:
require(plot3D)
par(mfrow = c(2, 1))
par(mar = c(0, 4, 4, 2))
plot(0, axes = FALSE, frame.plot = TRUE) # upper plot
par(mar = c(4, 4, 0, 2))
Col <- ramp.col(c("blue", "red"))
image2D(z = volcano, col = Col, xlab = "", contour = TRUE,
colkey = list(side = 1, length = 0.5))
Hope it helps,
Karline Soetaert
