nSpectralDensities: Spectral Density functions of n graphs

In BioNetStat: Biological Network Analysis

Description

Returns the spectral densities for a list of adjacency matrices at the same points

Usage

nSpectralDensities(A, from = NULL, to = NULL, bandwidth = "Silverman")

Arguments

A	a list of adjacency matrices
from	the lower value used to build the distribution
to	the higher value used to build the distribution
bandwidth	a parameters. It can be set to either "Sturges" or "Silverman".

Value

a list containing the components 'x' and 'densities'. The first element is the vector 'x' of 'npoints' coordinates of the points where the density function i estimated, and the second is a vector 'y' of the estimated density values.

A<-list()
A[[1]]<-as.matrix(as_adj(erdos.renyi.game(30,0.6,directed = FALSE)))
A[[2]]<-as.matrix(as_adj(barabasi.game(30,power = 1,directed = FALSE)))
A[[3]]<-as.matrix(as_adj(watts.strogatz.game(1,30,2,0.3)))
d<-nSpectralDensities(A, bandwidth="Sturges")
