degreedist.egor function

Plotting the degree distribution of an egocentric dataset

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.

## 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 asbrgmod, 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().

Returns

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)
