Active bindings

samplingRate

The percentage of observed dyads

nbNodes

The number of nodes

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

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.
