R Documentation

Plotting the degree distribution of an egocentric dataset

Description

A degreedist() method for egodata objects: plot a histogram of the degree distribution of actors in the egocentric dataset, optionally broken down by group and/or compared with a Bernoulli graph.

Usage

## S3 method for class 'egor'
degreedist(
  object,
  freq = FALSE,
  prob = !freq,
  by = NULL,
  brgmod = FALSE,
  main = NULL,
  plot = brgmod,
  weight = TRUE,
  ...
)

Arguments

`object`	A `egor` object.
`freq`, `prob`	Whether to plot the raw frequencies or the conditional proportions of the degree values. Defaults to the latter.
`by`	A character vector giving the name of a vertex attribute; if given, plots the frequences broken down by that attribute.
`brgmod`	Plot the range of predicted frequencies/probabilities according to a Bernoulli graph having the same expected density as the observed.
`main`	Main title of the plot.
`plot`	Whether to plot the histogram; defaults to the same value as`brgmod`, i.e., `FALSE`.
`weight`	Whether sampling weights should be incorporated into the calculation (`TRUE`, the default) or ignored (`FALSE`).
`...`	Additional arguments to `simulate.ergm.ego()`.

Value

Returns either a vector of degree frequencies/proportions if by=NULL or a matrix with a row for each category if not. If plot==TRUE returns invisibly.

Examples


data(faux.mesa.high)
fmh.ego <- as.egor(faux.mesa.high)

degreedist(fmh.ego,by="Grade",brgmod=TRUE)
# Compare:
degreedist(faux.mesa.high)
