Hi!

If you have a Spatial Points Data Frame, you can use the following function
to create a grid:

create1 <- function(obj) {

# Function that creates a new_data object if one is missing

        convex_hull = chull(coordinates(obj)[,1],coordinates(obj)[,2])

        convex_hull = c(convex_hull, convex_hull[1]) # Close the polygon

        d = Polygon(coordinates(obj)[convex_hull, ])

        new_data = spsample(d, 20, type = "regular")

        gridded(new_data) = TRUE

        return(new_data)

}



Hope this helps!


Sincerely,

Erin
