In the code/output below Node 153 has one neighbor (Node 156) but the
degree function returns 2. Does anyone know why this would happen? The
code for reading in g is included below and I took out loops so it
shouldn't be joined to itself.
> j <- 153
> neighbors(g,j)
[1] 156
> degree(g,j)
[1] 2
g <- read.graph("EL.txt", format=c("edgelist"))
g <- simplify(g, remove.multiple = TRUE, remove.loops = TRUE)
g <- delete.vertices(g,which(degree(g) < 1)-1)
I'm using iGraph in R.
Thank you,
Thomas
