r - Find name of node associated with maximum degree in igraph data frame -


i using igraph package find degree of each node (the built in degree(g) function) , returns numeric vector. how can tell node has maximum degree (not value node name)?

if have igraph data frame g, can create true/false vector degree(g)==max(degree(g)). can use find name of node(s) meet criteria - v(g)$name[degree(g)==max(degree(g))].

i created small example illustrate:

library(igraph) df = data.frame(node1=c("bob", "jim", "dave", "dave"),                 node2=c("jane", "john", "sally", "al"))  g = graph.data.frame(df) v(g)$name[degree(g)==max(degree(g))] [1] "dave"

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
