Hey everyone,
I have a small problem understanding how matrices are accessed.
I created 2 matrices:
data <- structure(c("A", "B", "C", "D", "D", "E", "H", "H", "H", "I",
"F", "G", "F", "F", "G", "G", "F", "G", "I", "J"),
.Dim = c(10L, 2L), .Dimnames = list(NULL, c("source",
"target")))
layout <- structure(c(-3.26366930571836, -5.50712710968822, -0.551118328281495,
-3.37122322327009, -5.66968864118556, -2.33181335195352, -0.48117505795906,
-7.44294029152183, -9.97273217503719, -8.78752994522558, -8.32625987988611,
-5.19337297863283, -1.01252729738437, -2.2253279705488, -8.08918461763048,
-5.09532606864114, -3.15827376499008, -1.940378485401,, 0.600378834777586,
3.57175093511171),
.Dim = c(10L, 2L), .Dimnames = list(NULL, c("coordinate.1",
"coordinate.2")))
my problem occurs when I try to plot a network:
base.net <- graph.edgelist(data, directed=FALSE)
plot(base.net, layout=layout)
The network needs to be structured in a very specific way and I don't
understand in which order the coordinates I created are assigned to the nodes.
(All nodes are labeled A-J. The coordinates aren't assigned alphabetically or
in the order of occurrence in the data matrix).
I hope someone can help me out. Thanks in advance!
