Convert Data Structures to rang edgelist

Description

This generic function converts several data structures provided by rang into an edgelist of package dependencies.

Usage

convert_edgelist(x, ...)

## Default S3 method:
convert_edgelist(x, ...)

## S3 method for class 'ranglet'
convert_edgelist(x, ...)

## S3 method for class 'rang'
convert_edgelist(x, ...)

Arguments

x,	supported data structures are rang and ranglet S3 objects
...,	not used

Details

the resulting data frame can be converted to an igraph object for plotting and analysis via the function igraph::graph_from_data_frame()

Value

a data frame of directed edges of dependencies

Examples

if (interactive()) {
    graph <- resolve(pkgs = c("openNLP", "LDAvis", "topicmodels", "quanteda"),
                snapshot_date = "2020-01-16")
                
    # dependency edgelist of a single package
    convert_edgelist(graph$ranglets[[1]])
    
    # full dependency edgelist
    convert_edgelist(graph)
}
