In mikejacktzen/datzen:

coordinate_nb: The coordinate_nb() function returns spatial neighborhoods in a coordinate triplet format

Usage

coordinate_nb(foo_spdf, style = "B", dir_out = NULL, ...)

Arguments

Argument |Description ------------- |---------------- foo_spdf | an object of class SpatialPolygonsDataFrame style | an optional character representing the style of spatial weights The same 'style' arg in nb2listw dir_out | an optional character representing the output directory if the user wishes to write to a '.csv' ... | optional arguments passed to nb2listw

Details

If dir_out=NULL (the default), then a data.frame of (i,j,k) coordinate triplets is returned to the environment. See listw2sn for more details. Otherwise a '.csv.' will be created at the specified destination path.

Value

A data.frame of the nb-coordinate triplets ("from","to","weights") with 'spatial.neighbour' class returned from listw2sn

Examples

```r example(columbus,package="spdep") out_ijk = coordinate_nb(foo_spdf=columbus, zero.policy=TRUE)

# above output is in coordinate structure # below converts to adjacency matrix mat_adj = spdep::as.spam.listw(sn2listw(out_ijk)) ```
