readMultiplex | R Documentation |
This functions uses readNetwork()
to read files that represent network layers that can be
different interaction types, represented by the type attribute of the igraph object.
readMultiplex( fileName, types = c("Competitive", "Mutualistic", "Trophic"), filePath = NULL, fhead = TRUE, skipColumn = 1, format = "layers" )
fileName |
vector of fileNames with the layers of the networks |
types |
vector of types that represent the layers |
filePath |
path of the files NULL by default |
fhead |
TRUE if the files have header fields, FALSE otherwise. |
format |
string, "layers" is the default were diferent layers are coded as different files there must be the same number of files as the length of the types vector as each type represent a layer. "GLV" Represent multiple intarction types as pairs of entries in a matrix so competition is represented as ai,j= -1, aj,i=-1, predation ai,j=1,aj,i=-1 where species j is the predator. Mutualism is ai,j=aj,i=1. Any negative or positive number works because intensity of interactions are not registered. |
skipColum |
integer, number of columns that are skiped 1 by default |
an mgraph object that is a list of igraph objects with the type attribute set to each kind of layer or interaction
