nbDyads

The number of dyads

is_directed

logical indicating if the network is directed or not

networkData

The adjacency matrix of the network

covarArray

the array of covariates

covarMatrix

Methods

Public methods

• partlyObservedNetwork$new()

• partlyObservedNetwork$clustering()

• partlyObservedNetwork$imputation()

• partlyObservedNetwork$clone()

Method new()

constructor

Usage

partlyObservedNetwork$new(
  adjacencyMatrix,
  covariates = list(),
  similarity = l1_similarity
)

Arguments

adjacencyMatrix

The adjacency matrix of the network

covariates

A list with M entries (the M covariates), each of whom being either a size-N vector or N x N matrix.

similarity

An R x R -> R function to compute similarities between node covariates. Default is l1_similarity, that is, -abs(x-y).

Method clustering()

method to cluster network data with missing value

Usage

partlyObservedNetwork$clustering(
  vBlocks,
  imputation = ifelse(is.null(private$phi), "median", "average")
)

Arguments

vBlocks

The vector of number of blocks considered in the collection.

imputation

character indicating the type of imputation among "median", "average"

Method imputation()

basic imputation from existing clustering

Usage

partlyObservedNetwork$imputation(type = c("median", "average", "zero"))

Arguments

type

a character, the type of imputation. Either "median" or "average"

Method clone()

The objects of this class are cloneable with this method.

Usage

partlyObservedNetwork$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
