This is an R package to analize ecological networks, including multilayer networks, recently developed network metrics and also some old ones conveniently in the same place. Functions to read, plot and a big set of networks are also included in the package.
require(devtools)
install_github("lsaravia/multiweb")Read the example data included in the package
require(multiweb)
fileName <- c(system.file("extdata", package = "multiweb"))
fileName <- system.file("extdata", "BarentsBoreal_FW.csv", package = "multiweb")
g <- readNetwork(fileName)
Read multiple interaction network in different layers as a list
fileName <- c(system.file("extdata", package = "multiweb"))
dn <- list.files(fileName,pattern = "^Kefi2015.*\\.txt$")
g <- readNetwork(dn,fileName, skipColumn = 2)Convert to mgraph type
gt <- fromIgraphToMgraph(g,c("Negative","Positive","Antagonistic"))
Read multiple interaction network with a function
types <- c("Negative","Positive","Antagonistic")
gt <- readMultiplex(dn,types,fileName, skipColumn = 2)
Calculate QSS (quasi-sign-stability) for multiple interactions networks (mgraph)
calc_QSS(gt)
