as_graph: Convert between graphicalMCP, gMCP, and igraph graph classes

In graphicalMCP: Graphical Multiple Comparison Procedures

Convert between graphicalMCP, gMCP, and igraph graph classes

Description

Graph objects have different structures and attributes in graphicalMCP, gMCP, and igraph R packages. These functions convert between different classes to increase compatibility.

Note that igraph and gMCP have additional attributes for vertices, edges, or a graph itself. These conversion functions only handle attributes related to hypothesis names, hypothesis weights and transition weights. Other attributes will be dropped when converting.

Usage

as_initial_graph(graph)

## S3 method for class 'graphMCP'
as_initial_graph(graph)

## S3 method for class 'igraph'
as_initial_graph(graph)

as_graphMCP(graph)

## S3 method for class 'initial_graph'
as_graphMCP(graph)

as_igraph(graph)

## S3 method for class 'initial_graph'
as_igraph(graph)

Arguments

graph

An initial_graph object from the graphicalMCP package, a graphMCP object from the gMCP package, or an igraph object from the igraph package, depending on the conversion type.

Value

• as_graphMCP() returns a graphMCP object for the gMCP package.

• as_igraph() returns an igraph object for the igraph package.

• as_initial_graph() returns an initial_graph object for the graphicalMCP package.
