nDegreeDensities: Density functions of the degrees of n graphs

In jardimViniciusC/BioNetStat: Biological Network Analysis

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.
