Fetch system requirements for a set of R packages

Uses remotes::system_requirements() to retrieve Ubuntu/Debian apt package names required by a set of R packages. Returns a deduplicated character vector of bare apt package names suitable for passing to apt-get install. Warns and returns an empty character vector if the lookup fails.

Usage

.fetch_sysreqs(packages, os_version = "22.04", verbose = FALSE)

Arguments

packages

A character vector of R package names.

os_version

A character string. The Ubuntu version to query against. Defaults to "22.04" when this function is called directly. generate_dockerfile() never relies on that default (C14): it always passes an explicit os_version, derived from the resolved r_version via .resolve_os_version() unless its own os_version argument overrides that derivation, since a single hardcoded value here only matched the Ubuntu release actually backing some R versions and not others.

verbose

Logical. If TRUE, prints progress messages.

Value

A deduplicated character vector of apt package names.
