Download and Parse Dependencies of an R Package — download_and_parse

Downloads a package from a repository, extracts it, and parses dependencies from the DESCRIPTION file.

Usage

download_and_parse_dependencies(
  package_name,
  version = NA,
  get_license = FALSE
)

Arguments

package_name: Name of the package to download.
version: Package version to download (default: `NA` for latest).
get_license: Whether to extract license information (default: `FALSE`).

Value

When `get_license = FALSE`, a data frame with columns `package`, `type`, and `parent_package`. When `get_license = TRUE`, a list with: - `dependencies`: Data frame of direct dependencies. - `license`: License of the specified package only (not dependencies). Returns `NA` if not found.

Details

The `license` field refers only to the package specified by `package_name`, not its dependencies. Use `build_dependency_tree()` or `fetch_all_dependencies()` with `get_license = TRUE` for full license information.

Examples

if (FALSE) { # \dontrun{
download_and_parse_dependencies("dplyr")
download_and_parse_dependencies("dplyr", get_license = TRUE)
} # }
