SharedBMat function

Shared boundary matrix

This function calculates the shared boundary matrix

SharedBMat(sf_pol, rn = FALSE)

Arguments

• sf_pol: spatial polygons, spatial lines object or spatial data frame
• rn: logical, default FALSE. If TRUE, the spatial weights matrix is row-normalized

Returns

• W: spatial weights matrix (length of shared boundary between spatial units)

Examples

library("sf")

ger   <- st_read(system.file("shape/GermanyNUTS3.shp",
                             package = "SDPDmod"),
                 quiet = TRUE)
bav <- ger[which(substr(ger$NUTS_CODE,1,3)=="DE2"),] ## Bavarian districts
W     <- SharedBMat(bav)
