Hello List,
I have to attach node attributes which I have stored in a matrix like:
id posts threads zindex
"u32" "123" "12" "0.45"
is there anything faster than this:
for(mm in V(gTorgo)[which(V(gTorgo)$type==FALSE)]$name){
list<-torgoValues[which(torgoValues[,1]==mm),]
V(gTorgo)[which(V(gTorgo)$name==mm)]$post<-as.numeric(list[2])
V(gTorgo)[which(V(gTorgo)$name==mm)]$thread<-as.numeric(list[3])
V(gTorgo)[which(V(gTorgo)$name==mm)]$zindex<-as.numeric(list[4])
}
my code is particularly slow on big networks... thanks!
Best,
Simone
