Attributing a spatial data frame using another spatial data frame

Description

This function will take a SpatialPoints/PolygonsDataFrame and add one attribute fields from a second SpatialPoints/PolygonsDataFrame

Usage

attribute.shapefile(
  spdf1,
  spdf2,
  attributefield = NULL,
  newfield = NULL,
  projection = sp::CRS("+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs")
)

Arguments

spdf1	A SpatialPoints/PolygonsDataFrame containing the geometry to add an attribute to
spdf2	A SpatialPoints/PolygonsDataFrame containing the geometry to add an attribute from
attributefield	The name of the field in spdf2 as a string containing the values to add to spdf1
newfield	The name of the field in spdf1 as a string to add the values from spdf2$attributefield to. If NULL, the field will use attributefield. Defaults to NULL.
projection	An sp::CRS() argument to apply in the event that spdf1 and spdf2 have different projections. Defaults to CRS("+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs")

Value

The original SPDF spdf1 with the new field containing the values inherited from spdf2.

Examples
