getLoadingNamespace returns information about the loading namespace. It is a wrapper to loadingNamespaceInfo, that does not throw an error.

getLoadingNamespace(env = FALSE, info = FALSE, nodev = FALSE)

isLoadingNamespace(ns, nodev = FALSE)

isNamespaceLoaded2(ns)

isDevNamespace(ns)

addNamespaceExport(x)

ns_get(x, ns = NULL, ...)

extra arguments passed to get0.

Value

the name of the loading namespace if env and info are FALSE, an environment if env=TRUE, a list with elements pkgname and libname if info=TRUE.

Functions

  • isLoadingNamespace: Tests if a namespace is being loaded.

  • isNamespaceLoaded2: tests if a given namespace is loaded, without loading it, contrary to isNamespace. It is similar to isNamespaceLoaded -- which it uses -- but also accepts environments.

  • isDevNamespace: tests the -- current -- namespace is a devtools namespace.

  • addNamespaceExport: Dynamically adds exported objects into the loading namespace.

  • ns_get: gets an object from a given namespace.
