permuteLabels - Permute the node labels of a tree
Description¶
permuteLabels permutes the node annotations of a lineage tree.
Usage¶
permuteLabels(graph, field, exclude = c("Germline", NA))
Arguments¶
- graph
- igraph object containing an annotated lineage tree.
- field
- string defining the annotation field to permute.
- exclude
- vector of strings defining
fieldvalues to exclude from permutation.
Value¶
A modified igraph object with vertex annotations permuted.
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")
