build_network.cranly_db {cranly}

Compute edges and nodes of package directives and collaboration networks

Description

Compute edges and nodes of package directives and collaboration networks

Usage

## S3 method for class 'cranly_db'
build_network(object, trace = FALSE, perspective = "package", ...)

Arguments

object

a cranly_db object. If missing (default) a call to clean_CRAN_db() is issued.

trace

logical. Print progress information? Default is FALSE.

perspective

character. Should a "package" (default) or an "author" network be built?

...

Other arguments passed in clean_CRAN_db() when object is NULL.

Details

The convention for a cranly_network object with perspective = "package" is that the direction of an edge is from the package that is imported by, suggested by, enhances or is a dependency of another package, to the latter package. The author collaboration network is analyzed and visualized as undirected by all methods in cranly.

Value

A list of 2 data.frame objects with the edges and nodes of the network.
