Hi,
If your object's points are regularly spaced and in a SpatialPoints
object, use:
gridded(myobj) = TRUE
Or you can from a data.frame with the coordinates and attributes to a
grid by:
coordinates(myobj) = ~x+y
gridded(myobj) = TRUE
or shorthand:
gridded(myobj) = ~x+y
cheers,
Paul

I would like to coerce this into a grid object so that I can overlay points
onto it. How exactly could I accomplish that? Thank you!!
