Examples

# Define and plot example graph
library(igraph)
graph <- ExampleTrees[[23]]
plot(graph, layout=layout_as_tree, vertex.label=V(graph)$c_call, 
     vertex.size=50, edge.arrow.mode=0, vertex.color="grey80")

# Permute annotations and plot new tree
g <- permuteLabels(graph, "c_call")
plot(g, layout=layout_as_tree, vertex.label=V(g)$c_call,
     vertex.size=50, edge.arrow.mode=0, vertex.color="grey80")
