sienaDataCreate: Function to create a Siena data object

In RSienaTest: Siena - Simulation Investigation for Empirical Network Analysis

Description

Creates a Siena data object from input dependent variables (networks and possibly behavioural variables), covariates, and composition change objects.

Usage

sienaDataCreate(..., nodeSets=NULL, getDocumentation=FALSE)

Arguments

...	objects of class sienaDependent, coCovar, varCovar, coDyadCovar, varDyadCovar, and/or sienaCompositionChange. There should be at least one sienaDependent object.
nodeSets	list of Siena node sets. Default is the single node set named "Actors", length equal to the number of rows in the first object of class "sienaDependent". If the entire data set contains more than one node set, then the node sets must have been specified in the creation of all data objects mentioned in ....
getDocumentation	Flag to allow documentation of internal functions, not for use by users.

Details

The function checks that the objects fit, that there is at least one network, and adds various attributes to each dependent variable describing the data. If there is more than one nodeSet they must all be specified. Function print01Report will give a basic description of the data object and is a check useful, e.g., for diagnosing problems.

Value

An object of class "siena" which is designed to be used in a siena model fit. The components of the object are.

nodeSets	List of node sets involved
observations	Integer indicating number of waves of data
depvars	List of networks and behavior variables
cCovars	List of constant covariates
vCovars	List of changing covariates
dycCovars	List of constant dyadic covariates
dyvCovars	List of changing dyadic covariates
compositionChange	List of composition change objects corresponding to the node sets

Examples

mynet <- sienaDependent(array(c(s501, s502, s503), dim=c(50, 50, 3)))
mybeh <- sienaDependent(s50a, type="behavior")
mydata <- sienaDataCreate(mynet, mybeh)
## And for a two-mode network
mynet1 <- sienaDependent(array(c(s501, s502), dim=c(50, 50, 2)), nodeSet="senders")
senders <- sienaNodeSet(50, nodeSetName="senders")
receivers <- sienaNodeSet(30, nodeSetName="receivers")
mynet2 <- sienaDependent(array(c(s501[,1:30], s502[,1:30]), dim=c(50, 30, 2)),
      nodeSet=c("senders", "receivers"))
(mydata <- sienaDataCreate(mynet1, mynet2, nodeSets=list(senders, receivers)))
## Not run: 
print01Report(mydata, modelname = "mydescription")

## End(Not run)
