Dear list members,

I am trying to plot point on a map using teh following code.

> library(raster)> library(rasterVis)> r = raster(jabali$map)> p = gplot(r) + geom_tile(aes(fill = value)) + geom_point(loc, aes(X,Y))Error: ggplot2 doesn't know how to deal with data of class uneval


I can plot the map, but I can get to plot the points on the map.  The
object "loc" is a data frame with the locations given by X and Y.


Best,


Manuel
