Install system dependencies for an R package

This function uses a shared cache approach with safe concurrency controls:

• Preserves shared pak cache to avoid redundant downloads/builds

• Uses operation-specific mutexes to prevent cache corruption

• Implements retry logic with exponential backoff for transient failures

• Cleans up stale lock files automatically

Usage

install_pkg_sys_deps(
  package_name,
  tag,
  local_clone_dir,
  platform = platform,
  aggressive_cleanup = FALSE
)

Arguments

package_name

(character)
Package name

tag

(character)
Tag/version. Tags starting with "R-" are filtered out.

local_clone_dir

(character)
Path to clone git repos into

platform

(character)
Platform identifier

aggressive_cleanup

(logical)
Perform additional cache cleanup before installation

Details

The shared cache approach is preferred over isolation because:

• Avoids redundant package downloads across builds

• Reduces storage requirements and build times

• Maintains cache benefits while ensuring thread safety
