Map GPS points to polygon regions
Usage
mapPoints(data, geo, long, lat, names)
Arguments
- data
point data with two columns of GPS locations.
- geo
SpatialPolygonsDataFrame of the map
- long
column name for longitudinal coordinate in the data
- lat
column name for latitude coordinate in the data
- names
character vector of region ids to be added to the neighbours list
Value
Spatial djacency matrix.
Examples
data(DemoMap)
dat <- data.frame(ID = c(1,2,3), lon = c(32.2, 33.7, 33), lat = c(0.1, 0.9, 2.8))
dat2 <- mapPoints(dat, DemoMap$geo, long = "lon", lat = "lat", names = "REGNAME")
dat2
#> ID lon lat REGNAME
#> 1 1 32.2 0.1 central
#> 2 2 33.7 0.9 eastern
#> 3 3 33.0 2.8 northern
