Document precompute_topological_sorts function

[Copilot]

The precompute_topological_sorts function had inaccurate documentation: the description mentioned a non-existent "output directory" parameter, and the @return section incorrectly stated it returns a number instead of a list.

Changes

• Description: Removed reference to non-existent output directory. Added explanation that topological sorts are "consistent orderings of items that respect pairwise preference constraints"

• Return value: Changed from "returns the number of topological sorts" to properly document the list structure:

  • sort_count: integer with total number of sorts
  • sort_matrix: matrix where each column is a topological sort

• CRAN compliance: Changed backticks to \code{} markup in details section

Example output

The documented example now correctly demonstrates both modes:

sorts <- precompute_topological_sorts(prefs = as.matrix(prefs), n_items = 5, save_frac = 0)
sorts$sort_count  # 12
sorts$sort_matrix # <0 x 0 matrix>

sorts <- precompute_topological_sorts(prefs = as.matrix(prefs), n_items = 5, save_frac = 1)
sorts$sort_count  # 12
sorts$sort_matrix # <5 x 12 matrix>

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cloud.r-project.org
  • Triggering command: /usr/lib/R/bin/exec/R /usr/lib/R/bin/exec/R --no-echo --no-restore -e install.packages(c('Rcpp',~+~'RcppArmadillo',~+~'testthat',~+~'roxygen2'),~+~repos='REDACTED') (dns block)
• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
