[R] Axes in filled.contour plots [Solved]

I should let you guys know that I figured this whole axes on filled contour
plots issue out. This might not be the most elegant solution but it will
work me:

filled.contour(contour, axes=F, frame.plot=TRUE, color=terrain.colors, ylab=
"Length Along Flume (m)", key.title = title(main="Velocity\n(m/s)"),
key.axes = axis(4, seq(0, 0.6, by = 0.1)), plot.axes = {
axis.mult(side=1,mult=0.005,mult.label="Width (cm)")
axis(side=2, at=x, labels=colnames(contour)) })

Thanks for your help.
