Project integration points to mesh vertices — fm_vertex

Compute information for assigning points to the vertices of the covering triangle

Usage

fm_vertex_projection(points, mesh)

Arguments

points: A SpatialPointsDataFrame, sf, or list object
mesh: An fm_mesh_2d or inla.mesh object

Value

SpatialPointsDataFrame, sf, or list of mesh vertices with projected data attached

Examples

head(fm_vertex_projection(list(loc = fmexample$loc), fmexample$mesh))
