You are plotting the entire lattice plot (including axes, margins etc)
in the grid viewport. What you want to do is to call the panel
function, panel.levelplot(), instead.
However, why not just
mm <- map('worldHires', plot = FALSE)
levelplot(z~x+y,xyz, mm = mm, panel = function(..., mm) {
pan
You don't have to use map() to draw the map.
m <- map(..., plot = FALSE)
xyplot(y ~ x, m, type = "l", aspect = "iso",
par.settings = list(axis.line = list(col = "transparent")))
or inside a panel function, assuming appropriate scales:
panel.xyplot(m$x, m$y, ...)
