flowjointure {cartograflow} | R Documentation |
Builds a spatial join with a flow dataset
Description
Builds a spatial join between a flow dataset and a spatial features layer (as a map background)
Usage
flowjointure(geom, bkg, DF.flow, origin, destination, DF.point, id, x, y)
Arguments
geom |
the geometry of the spatial features layer: points or areas |
bkg |
the spatial features layer |
DF.flow |
the input flow dataset as a dataframe |
origin |
the place of origin code |
destination |
the place of destination code |
DF.point |
a dataframe of points or places |
id |
dataframe of points or places file code |
x |
the X coordinate of the point or places |
y |
the Y coordinate of the point or places |
Value
the corresponding joint table between the flow dataset and the spatial feature layer
Examples
library(cartograflow)
library(sf)
data(flowdata)
map <- st_read(system.file("shape/MGP_TER.shp", package = "cartograflow"))
tabflow <- flowjointure(
geom = "area", bkg = map, DF.flow = flows, origin = "i", destination = "j",
id = "EPT_NUM", x = "X", y = "Y"
)
