R Documentation

Generate an evolving random graph with preferential attachment and aging

Description

aging.barabasi.game() was renamed to sample_pa_age() to create a more consistent API.

Usage

aging.barabasi.game(
  n,
  pa.exp,
  aging.exp,
  m = NULL,
  aging.bin = 300,
  out.dist = NULL,
  out.seq = NULL,
  out.pref = FALSE,
  directed = TRUE,
  zero.deg.appeal = 1,
  zero.age.appeal = 0,
  deg.coef = 1,
  age.coef = 1,
  time.window = NULL
)

Arguments

`n`	The number of vertices in the graph.
`pa.exp`	The preferential attachment exponent, see the details below.
`aging.exp`	The exponent of the aging, usually a non-positive number, see details below.
`m`	The number of edges each new vertex creates (except the very first vertex). This argument is used only if both the `out.dist` and `out.seq` arguments are NULL.
`aging.bin`	The number of bins to use for measuring the age of vertices, see details below.
`out.dist`	The discrete distribution to generate the number of edges to add in each time step if `out.seq` is NULL. See details below.
`out.seq`	The number of edges to add in each time step, a vector containing as many elements as the number of vertices. See details below.
`out.pref`	Logical constant, whether to include edges not initiated by the vertex as a basis of preferential attachment. See details below.
`directed`	Logical constant, whether to generate a directed graph. See details below.
`zero.deg.appeal`	The degree-dependent part of the ‘attractiveness’ of the vertices with no adjacent edges. See also details below.
`zero.age.appeal`	The age-dependent part of the ‘attrativeness’ of the vertices with age zero. It is usually zero, see details below.
`deg.coef`	The coefficient of the degree-dependent ‘attractiveness’. See details below.
`age.coef`	The coefficient of the age-dependent part of the ‘attractiveness’. See details below.
`time.window`	Integer constant, if NULL only adjacent added in the last `time.windows` time steps are counted as a basis of the preferential attachment. See also details below.
