I have a graph with names from 1 to 10
library(igraph)
library(Cairo)
g<- graph(c(0,1,0,4,0,9,1,7,1,9,2,9,2,3,2,5,3,6,3,9,4,5,4,8,5,8,6,7,6,8,7,8),n=10,dir=FALSE)
V(g)$name<-c(1:10)
V(g)$label<-V(g)$name
coords <- c(0,0,13.0000,0,5.9982,5.9991,7.9973,7.0009,-1.0008,11.9999,0.9993,11.0002,7.9989,13.0009,10.9989,14.0009,5.9989,14.0009,7.0000,4.0000)
coords <- matrix(coords, 10,2,byrow=T)
plot(g,layout=coords)
listMn<-neighborhood(g,1,0:9)
I'd like to do this but in opposite way
m1<-V(g)[listMn[[7]]]$name
the above instructions gets,
7 4 8 9
how to get listMn[[7]]=6 3 7 8 from names 7 4 8 9?
