Subject: Problem with shortestPath in igraph and qgraph
hello,
I have a graph and i use qgraph package to calculate centrality parameters.
Now I want to know the maximum value of shortest path for each vertex with
discarding the Inf value in short pathes. For this I use the
ShortestPathLengths of centrality function in qgraph. but when I want to
get the maximum the result is wrong. here is my code:
cen<-centrality(Q)
tmp3<-cen$ShortestPathLengths
shp<-matrix(1:ncol(tmp3),ncol(tmp3),1)for(i in ncol(tmp3)){
shp[i,]=max(tmp3[i,][tmp3[i,]!=Inf)}
when I display the valu of shp the result is same as initial value (form
one to ncol). I also test with shortest.paths function. the result was
same. what is my wrong?
