1 | packageName(env = parent.frame())

env |
The environment whose name we seek. |
Environment env would be associated with a package if topenv(env) is the namespace environment for that package. Thus when env is the environment associated with functions inside a package, or local functions defined within them, packageName will normally return the package name.
Not all environments are associated with a package: for example, the global environment, or the evaluation frames of functions defined there. packageName will return NULL in these cases.
A length one character vector containing the name of the package, or NULL if there is no name.
getPackageName
is a more elaborate
function that can construct a name if none is found.
