Adjusting the node size in igraph using a matrix

Question

I have the following network diagram:

set.seed(1410)
df<-data.frame(
\"site.x\"=c(rep(\"a\",4),rep(\"b\",4),rep(\"c\",4),rep(\"d\",4)),
\"site.y\"=c(rep(c         


        

Answer 1

You could use

node.size<-setNames(c(25, 15, 35, 5, 10, 5, 19, 44),c("a", "b","c", "d", "e", "f", "g", "h"))
plot(df,layout=l,vertex.label=V(df)$names,
edge.arrow.size=0.01,vertex.label.color = "black",vertex.size=node.size)

so basically a named vector.

plot(df,layout=l,vertex.label=V(df)$names,
edge.arrow.size=0.01,vertex.label.color = "black",vertex.size=as.matrix(node.size) )

would also work

UPDATE:

If you need to use your m matrix

plot(df,layout=l,vertex.label=V(df)$names,
edge.arrow.size=0.01,vertex.label.color = "black",vertex.size=m[m!=0])
