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?
