Import a function from another package

Source: R/use_import_from.R
use_import_from.Rd

use_import_from() imports a function from another package by adding the roxygen2 @importFrom tag to the package-level documentation (which can be created with use_package_doc()). Importing a function from another package allows you to refer to it without a namespace (e.g., fun() instead of package::fun()).

use_import_from() also re-documents the NAMESPACE, and re-load the current package. This ensures that fun is immediately available in your development session.

Usage

use_import_from(package, fun, load = is_interactive())

Arguments

package

Package name

fun

A vector of function names

load

Logical. Re-load with pkgload::load_all()?

Value

Invisibly, TRUE if the package document has changed, FALSE if not.

Examples

if (FALSE) { # \dontrun{
use_import_from("glue", "glue")
} # }
