I am following the examples over here on using the "statnet" library in http://personal.psu.edu/drh20/papers/v24i09.pdf.
The first example shows how to inspect a statnet network object in R:
library(statnet)
library(network)
data("faux.magnolia.high")
fmh <- faux.magnolia.high
summary(fmh)
In the above example, it seems here that the statnet network in this example already has "node attributes".
Using the statnet library, does anyone know if there is a way to directly create a network with node attributes from a data frame?
For example, if I have some data that looks like this:
mydata <-data.frame(
"source" = c("123","124","123","125","123"),
"target" = c("126", "123", "125", "122", "111"),
"color" = c("red","red","green","blue","red"),
"food" = c("pizza","pizza","cake","pizza","cake")
)
Suppose I had a pre defined list of node attributes:
Nodes <-data.frame(
"source" = c("123","124","125","122","111", "126"),
"Country" = c("usa", "uk", "uk", "usa", "uk", "usa")
)
I tried the following code:
net = network(mydata)
But I am not sure if this has created a network with the node attributes (color and food).
I also tried this, but it did not work:
mydata <-data.frame(
"source" = c("123","124","123","125","123"), "target" = c("126", "123", "125", "122", "111"), "color" = c("red","red","green","blue","red"), "food" = c("pizza","pizza","cake","pizza","cake") )
Nodes <-data.frame(
"source" = c("123","124","125","122","111", "126"),
"Country" = c("usa", "uk", "uk", "usa", "uk", "usa")
)
net<-network(mydata[,c[1:2])
edges <- as.sociomatrix(mydata[,c(3:4)],simplify=TRUE)
nodes <- as.sociomatrix(Nodes,simplify=TRUE)
final <- as.sociomatrix(list(net,edges,nodes))
Can someone please show me how to create a network with node attributes?

Thanks
Could this be the answer? https://igraph.org/r/doc/graph_from_data_frame.html
library(igraph)
g <- graph_from_data_frame(mydata, directed=TRUE, vertices=Nodes)
