It does not appear so by taking a rough looking at code for
filled.contour. You should consider using levelplot in package:lattice.
library(lattice)
x <- seq(pi/4, 5 * pi, length = 100)
y <- seq(pi/4, 5 * pi, length = 100)
r <- as.vector(sqrt(outer(x^2, y^2, "+")))
grid <- expand.grid(x=x, y=y)
grid$z <- cos(r^2) * exp(-r/(pi^3))
lset(theme = col.whitebg())
levelplot(z~x*y, grid, cuts = 50, scales=list(log="e"),
xlab="",
ylab="", main="Weird Function", sub="with
log scales",
colorkey = list(space = "bottom"), region = TRUE)
