 nDegreeDensities R Documentation

## Density functions of the degrees of n graphs

### Description

'nDegreeDensities' estimates the density functions of the degrees for n graphs at the same coordinates

### Usage

```nDegreeDensities(
Gs,
npoints = 1024,
bandwidth = "Sturges",
from = NULL,
to = NULL
)
```

### Arguments

 `Gs` a list of n igraph graphs objects `npoints` number of points used in density function estimation `bandwidth` a parameters. It can be set to either "Sturges" or "Silverman". `from` the lower value used to build the distribution `to` the higher value used to build the distribution

### 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.

`graph.strength`

`density`

### Examples

```G<-list()
G[]<-erdos.renyi.game(30,0.6)
G[]<-barabasi.game(30,power = 1)
G[]<-watts.strogatz.game(2,30,2,0.3)
d<-nDegreeDensities(G, npoints=1024, bandwidth="Sturges")
par(mfrow=c(1,3))
plot(d\$x,d\$densities[,1],main="Erdos-Renyi\n Degree distribution",
xlab="Degree",ylab="Frequency")
plot(d\$x,d\$densities[,2],main="Barabasi\n Degree distribution",
xlab="Degree",ylab="Frequency")
plot(d\$x,d\$densities[,3],main="Watts-Strogatz\n Degree distribution",
xlab="Degree",ylab="Frequency")
```
