nbdists {spdep} | R Documentation |
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.
nbdists(nb, coords, lonlat = FALSE)
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 |
A list with class nbdist
