## S3 method for class 'networkDynamic'
summary_formula(object, at, ..., basis = NULL)

Arguments

object

An formula object with a networkDynamic as its LHS. (See summary_formula for more details.)

at

A vector of time points at which to calculate the statistics.

Further arguments passed to or used by methods.

basis

An optional networkDynamic object relative to which the statistics should be calculated.

Value

A matrix with length(at) rows, one for each time point in at, and columns for each term of the formula, containing the corresponding statistics measured on the network.

# create a toy dynamic network

activate.vertices(my.nD, onset=0, terminus = 10)
add.edges.active(my.nD,tail=1:2,head=2:3,onset=5,terminus=8)

# use a summary formula to display number of isolates and edges
# at discrete time points
summary(my.nD~isolates+edges, at=1:10)
