In shp2graph: Convert a SpatialLinesDataFrame Object to an 'igraph'-Class Object

Description

A specific function to visualizethe integration between a point data set and spatila network, i.e. results returned by the function points2network

Usage

ptsinnt.view(ntdata, nodelist, pointsxy, CoorespondIDs, VElist=NULL)

Arguments

ntdata	A “SpatialLinesDataFrame” or “SpatialLines” object
nodelist	A “nodelist” object
pointsxy	A two-column matrix of point coordinates (X, Y)
CoorespondIDs	A vector of the cooresponding node ID for each point in “pointsxy”
VElist	A list of virtual edges if added, i.e. approaches 3 and 4 are used

Examples

data(ORN)
#pts<-spsample(ORN.nt, 100, type="random")
#ptsxy<-coordinates(pts)[,1:2]
#ptsxy<-cbind(ptsxy[,1]+0.008,ptsxy[,2]+0.008)
#Mapping each point to the nearest node in the network/graph
#res<-points2network(ntdata=ORN.nt,pointsxy=ptsxy, mapping.method=1)
#Visualize the results without virtual edges 
#ptsinnt.view(ntdata=ORN.nt, nodelist=res[[1]], pointsxy=ptsxy, 
#             CoorespondIDs=res[[3]])
#Visualize the results with virtual edges
#res<-points2network(ntdata=ORN.nt,pointsxy=ptsxy, mapping.method=3,
#                    ea.prop=rep(0,37))
#VElist<-res[[7]]
#ptsinnt.view(ntdata=ORN.nt, nodelist=res[[1]], pointsxy=ptsxy, 
#             CoorespondIDs=res[[3]], VElist=VElist)
