mergeEdgeLists: Merge edgelists => Master edgelist => igraph

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

Description

This function turns a list of edgelists (data.frames) into a single "master" edgelist. It maintains the edge attributes of each individual edge list

Usage

mergeEdgeLists(edgeLists, from = "from.ID", to = "to.ID", keepDups = F)

Arguments

edgeLists	list of edgelists (stored as data.frames)
from	name of the column that specifies the "from" node in each data.frame in edgeLists
to	name of the column that specifies the "to" node in each data.frame in edgeLists
keepDups	deletes duplicate from-to relations when set to FALSE

Examples

require('igraph')
cars <- data.frame(mtcars, to=sample(rownames(mtcars), replace=T), from=sample(rownames(mtcars), replace=T))
df1<-cars[sample(1:32,30), c('to', 'from', 'cyl', 'mpg')]
df2<-cars[sample(1:32,15), c('to', 'from', 'cyl', 'qsec')]
df3<-cars[sample(1:32,32), c('to', 'from', 'hp', 'drat')]

df1$cyl[1:10] <- df1$cyl[1:10]+2
el <- list(df1, df2, df3)

mel <- mergeEdgeLists(el, from='from', to='to', keepDups=T)
