summary.formula: Calculation of network or graph statistics or other...

Description Usage Arguments Details Value See Also Examples

Description

Most generally, this function computes those summaries of the object on the LHS of the formula that are specified by its RHS. In particular, if given a network as its LHS and ergm-terms on its RHS, it computes the sufficient statistics associated with those terms.

Usage

## S3 method for class 'formula'
summary(object, ...)

Arguments

object

A formula having as its LHS a network object or a matrix that can be coerced to a network object, a network.list, or other types to be summarized using a formula. (See ‘methods(’summary_formula') for the possible LHS types.

...

further arguments passed to or used by methods.

Details

In practice, summary.formula() is a thin wrapper around the summary_formula() generic, which dispatches methods based on the class of the LHS of the formula.

summary.formula for networks understands the lasttoggle "API".

Value

A vector of statistics specified in RHS of the formula.

# Lets look at the Florentine marriage data

data(florentine)
#
# test the summary_formula function
#
summary(flomarriage ~ edges + kstar(2))
m <- as.matrix(flomarriage)
summary(m ~ edges)  # twice as large as it should be
summary(m ~ edges, directed=FALSE) # Now it's correct
