In tributetotobler/ttt: Tribute to Tobler

Compute the mean vectors of an OD matrix

Description

Compute the mean vectors of an OD matrix

Usage

mean_od_vectors(pts, OD)

Arguments

pts	sf data.frame with point geometries
OD	an OD matrix with as many rows as pts

Value

An sf data.frame similar to pts with dx and dy columns that store the mean vectors.

Examples

# data(munich)
# sf=mean_od_vectors(munich$coords,minich$OD)
# ggplot(sf)+geom_segment(aes(x=x,y=y,xend=x+dx*100,yend=y+dy*100),arrow = arrow(angle=15,length = unit(0.3,"cm"),type = "closed"))+theme_void()
