You are using this wrong. In particular I'm completely confused by the
c(...) usage.
You probably want something like
panel = function(...) {
panel.levelplot(...)
panel.abline(h = 200)
}
since you are not using any of the arguments passed to the panel function
for the panel.abline call. If you do need to use something, say x, y, and
z, your usege should be:
panel = function(x, y, z, ...) {
panel.levelplot(x = x, y = y, z = z, ...)
## do something with x,y,z
hloc = foo(x, y, z)
panel.abline(h = hloc)
})
