nbdists: Spatial link distance measures

Description

Given a list of spatial neighbour links (a neighbours list of object type nb), the function returns the Euclidean distances along the links in a list of the same form as the neighbours list. If lonlat = TRUE, Great Circle distances are used.

Usage

nbdists(nb, coords, lonlat = FALSE)

Arguments

nb

an object of class nb

coords

matrix of point coordinates

lonlat

TRUE if point coordinates are longitude-latitude decimal degrees, in which case distances are measured in kilometers

Value

• A list with class nbdist

Examples

data(columbus)
dlist <- nbdists(col.gal.nb, coords)
dlist <- lapply(dlist, function(x) 1/x)
stem(unlist(dlist))
