In brooksandrew/Rsenal: Rsenal (arsenal) of assorted R functions developed over the years

Description

Returns a subset of the original graph (all edges and vertices that a directed path can take from from the root node. OrderN limits the growth of these paths.

Usage

travOut(g, root, orderN = -1)

Arguments

g	igraph object
root	character string: name of root node
orderN	number: # of degrees away from root node to search.

## build sample network
from <- c('A','A','B','B','C','C','D','D','E','E','E','F','F','H','L','L','O')
to <- c('B','C','D','E','F','G','H','I','J','J','K','L','G','M','N','O','P')
relations<-cbind(from,to)
g <- graph.data.frame(relations)
tiers <- c(1,2,3,4,1,3,4,2,1,2,3,4,0,0,1,2)
V(g)$tier <- tiers
