In szymanskir/cran-network: What the Package Does (One Line, Title Case)

Introduction

The goal of this notebook is to perform an initial analasis of the CRAN package network which will lead to a number of experiment ideas for future work. Two different types of package networks have been created:

• One based on the Suggests relation
• One based on both the Depends and Imports relation

Analysis

A basic summary of graph statistics is presented in the table below:

drake::readd(graphs_summary) %>% 
  knitr::kable() %>% 
  kableExtra::kable_styling(full_width = FALSE)

As we are investigating package dependencies only the in degrees will be considered. The histogram of in degrees for both graphs are depicted in the following pictures:

drake::readd(degree_hist_plot_suggests_graph) +
  drake::readd(degree_hist_plot_depends_graph)

Both graphs follow a power distribution and are on the less dense side. The difference between those graphs is that one is a DAG and the other is not, however this is not a surprise as the Depends graph should be a DAG while the suggests graph might contain crossdependcies between popular document and testing frameworks.
