Plot network using ggnet2

I have a network that I created by importing a gml file. If I plot this network using plot, nodes have the correct label (string). If I try to do the same thing using ggnet2, the labels become numbers. Why? This is my code:

   library(igraph)
   library(poweRlaw)
   library(sna)
   library(ggplot2)
   library(GGally)
   library(ergm)
   library(intergraph)

   net <- read.graph("./network.gml", format = c("gml"))

plot(net) netb <- asNetwork(net) ggnet2(netb, size = "degree", label = TRUE)

The results I get are: enter image description here enter image description here

Without seeing your data, it's most likely that read.graph is setting the vertex names to be numbers and that plot is grabbing the names from a different variable. The ggnet2 documentation explains that the label variable can be set to the name of the vertex attribute that you wish to use. Try changing label = TRUE to label="<VertexName>" where <VertexName>is the name of the vertex in netb that contains the labels.
