# **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**

```r
library("cranly")
```
and use instances of the package directives and author collaboration networks

```r
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

```r
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

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

<img src="precomp-extractors-unnamed-chunk-20-1.png" title="plot of chunk unnamed-chunk-20" alt="plot of chunk unnamed-chunk-20" width="100%" />

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

<img src="precomp-extractors-unnamed-chunk-20-2.png" title="plot of chunk unnamed-chunk-20" alt="plot of chunk unnamed-chunk-20" width="100%" />

or the word cloud of the titles of those packages are

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

<img src="precomp-extractors-unnamed-chunk-21-1.png" title="plot of chunk unnamed-chunk-21" alt="plot of chunk unnamed-chunk-21" width="100%" />

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

<img src="precomp-extractors-unnamed-chunk-21-2.png" title="plot of chunk unnamed-chunk-21" alt="plot of chunk unnamed-chunk-21" width="100%" />

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

```r
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)
```
