Faces occupied by the specified object

Description

This function will return a facelayer class object showing which faces are occupied by the input object.

Usage

occupied(gridObj, data, out = "logical", ...)

Arguments

gridObj	(trigrid or hexagrid) An icoshedral grid.
data	(matrix, data.frame or Spatial) The queried data.
out	(character) What shall be the output class? Can be either facelayer or logical (default.)
...	Arguments passed to the class specific methods

Details

This is a wrapper function on the OccupiedFaces methods that are specific to grid class and input data.

Value

The function Returns a facelayer-class object.

Examples

# create a grid
g <- trigrid(8, sf=TRUE)

# create random points
randPoints <- rpsphere(100,output="polar")

# the faces occupied by these points
occ <- occupied(g, randPoints)
 
 # plot using sf slot independently
plot(g@sf[occ,"geometry"])
points(randPoints, col="red", pch="+")
