Usage

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

isLoadingNamespace(ns, nodev = FALSE)

isNamespaceLoaded2(ns)

isDevNamespace(ns)

addNamespaceExport(x)

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

Arguments

env

logical that indicates that the namespace's environment (i.e. the namespace itself) should be returned.

info

logical that indicates that the complete information list should be returned

nodev

logical that indicates if loading devtools namespace should be discarded.

ns

the name of a namespace or a namespace whose loading state is tested. If missing isLoadingNamespace test if any namespace is being loaded.

x

character vector containing the names of R objects to export in the loading namespace.

...

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.

• isLoadingNamespace returns a logical flag.

• isNamespaceLoaded2 returns a logical flag.

• isDevNamespace returns a logical flag.

• ns_get returns the requested object or NULL if not found.

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.
