I have a question about the graph_from_data_frame function.
I have an edge list (el) that has 271 drugs as V1, and 6754 compounds as V2. But when I create a graph, g has just 10 nodes of only the first 10 drugs.
> length(unique(f$DRUG))
[1] 271
> length(unique(f$Compound_ID))
[1] 6754
> length(g)
[1] 10
el<-cbind(f$DRUG,f$Compound_ID, f$FC)
colnames(el)<-c("V1","V2", "weight")
g=graph_from_data_frame(el)
g <- set_edge_attr(g, "weight", value= f$FC)
What can be the problem?
Thanks in advance!
