# Extracting information from cranly package networks: extractors and word clouds

# cranly extractor functions

Since version 0.3, cranly includes functions for extracting information from `cranly_network` objects (see `?extractor-functions`). All extractor functions in `cranly` try to figure out what `y` is in the statements

`y` is [the] `extractor-function` a `package`/`author`

### CRAN package directives and author collaboration networks

Let’s attach cranly

    library("cranly")

and use instances of the package directives and author collaboration networks

    package_network <- readRDS(url("https://raw.githubusercontent.com/ikosmidis/cranly/develop/inst/extdata/package_network.rds"))
    author_network <- readRDS(url("https://raw.githubusercontent.com/ikosmidis/cranly/develop/inst/extdata/author_network.rds"))

from CRAN’s state on 2022-08-26 14:43:43 BST

Alternatively, today’s package directives and author collaboration networks can be constructed by doing

    cran_db <- clean_CRAN_db()
    package_network <- build_network(cran_db)
    author_network <- build_network(cran_db, perspective = "author")

# Word clouds

Since version 0.5 cranly provides methods to construct word clouds of either author names, package descriptions or package titles. For example, the word cloud of the descriptions of the packages maintained by me and Edzer Pebesma are

    word_cloud(package_network, maintainer = "Ioannis Kosmidis", exact = TRUE, min.freq = 1)

    word_cloud(package_network, maintainer = "Edzer Pebesma", exact = TRUE, min.freq = 1)

or the word cloud of the titles of those packages are

    word_cloud(package_network, maintainer = "Ioannis Kosmidis", perspective = "title", exact = TRUE,
               scale = c(2, 0.1), min.freq = 1)

    word_cloud(package_network, maintainer = "Edzer Pebesma", perspective = "title", exact = TRUE,
               scale = c(2, 0.1), min.freq = 1)

More complex queries can be achieved by using the extractor functions and computing the term frequencies manually. For example, the word cloud of all packages maintained by people with “warwick.ac.uk” in their email is

    warwick_emails <- package_network |> email_with("warwick.ac.uk", flat = FALSE)
    warwick_pkgs  <- warwick_emails$package
    descriptions <- package_network |> description_of(warwick_pkgs, exact = FALSE)
    term_frequency <- compute_term_frequency(descriptions)
    word_cloud(term_frequency, min.freq = 5)
