diagram.levels {multiplex}

Levels in the Lattice Diagram

Description

This is a function that reads the different levels in the lattice diagram of the partial order structure among actors and ties in the network

Usage

diagram.levels(x, perm = FALSE)

Arguments

x

A matrix representing the partial order

perm

(optional) whether or not to return the permuted structure

Details

When it comes to reduce the structure of a multiple network, many times the partial order structure provides different classes of elements depending in the inclusions these elements have. In this sense, the illustration given by the diagram function provides us typically with different levels of the ordered relations, which are read by this routine.

Value

A named list with components of the “levels” in the concept diagram produced by diagram.

If the permutation is specified, a data frame with the elements of the partial order structure with the column names indicating the element class plus a vector with the levels and a matrix with the permuted structure are given as well.

Note

This function requires that the Rgraphviz package is available. Besides, since the pictex function from grDevices is inside this routine, which may imply in some cases running with administrator privileges.

Examples

## load the data
data("incubA")

## given e.g. a partial order table in the object 'po'
po <- partial.order(as.strings(incubA$IM))

## find the levels in the lattice diagram
## Not run: diagram.levels(po)
