Problems with function gplot from rasterVis

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.

Hi Manuel,

Try this:

gplot(r) + geom_tile(aes(fill = value)) + geom_point(aes(X,Y), data=loc)

The arguments of geom_point are mapping and then data, but you were
using them in reverse order.

Best,

Oscar.
