# 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

 `1` ```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.

## See Also

`KLdegree`

`density`

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12``` ```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") par(mfrow=c(1,3)) plot(d\$x,d\$densities[,1],main="Erdos-Renyi\n Spectral distribution", xlab="Eigenvalue",ylab="Frequency") plot(d\$x,d\$densities[,2],main="Barabasi\n Spectral distribution", xlab="Eigenvalue",ylab="Frequency") plot(d\$x,d\$densities[,3],main="Watts-Strogatz\n Spectral distribution", xlab="Eigenvalue",ylab="Frequency") ```
