Sure. Using levelplot(..., contour=TRUE, region=FALSE, ...) or
contourplot(...)

Is it possible to get just the contours on top of the gmap?
If I use levelplot(...,contour=TRUE,...) I get the contours but
the filled levels as well.
Thanks

Hello,
Let's suppose that 'gmap' is the image resulting from a GetMap.bbox() call
and 'r' is your Raster*. A suitable solution is:
library(rasterVis)
levelplot(r) + layer_(grid.raster(gmap,
x=lonCenter,
y=latCenter,
Hi Scott,
You may be interested in the ggmap package; see

Scott, Here is an Incomplete answer but perhaps useful anyway. You can do:
library(dismo)
g <- gmap("Pacific Northwest National Laboratory, Richland, WA, USA")
plot(g)
# and now you can add points, polygons, lines.
# you can also do
library(rasterVis)
levelplot(g)
This "works" but not as desire
Hi,
I've learned the basics of using RgoogleMaps and rasterVis, and now I want to
combine their capabilities to use levelplot() with a georeferenced PNG image as
a background in the lattice panel. And, I want to plot to the normal R
graphics devices, not the web as package plotGoogleMaps does.
