ascribe

ascribe scans R projects for package and function use. Other packages can use the results to generate citations without maintaining their own parser.

Installation

You can install the development version of ascribe from GitHub with:

# install.packages("pak")
pak::pak("VisruthSK/ascribe")

Example

Build a package universe, then cite the code that uses it:

library(ascribe)

universe <- build_universe_data("stats")
usage <- scan_usage(path, universe$packages, universe$export_index, universe$origin_map)
cite_usage(usage)

Limitations

• The scanner records function calls, not function references. It ignores lapply(x, mean) and purrr::map(x, sd).
• Its built-in Markdown parser recognizes R chunks headed with {r}. Plain fenced blocks with an r info string are skipped.
• Package attachments are tracked within each file. A setup script that calls library() does not establish attachment state for another file.
• Default package citations require the package to be installed. Supply package_citations for packages that are unavailable locally.
• Scanning a namespace inspects its bindings for R6 classes. Active bindings can run their getters, and unusually deep generated expressions can exceed R’s recursion limits.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
