lib_unload: Unload a Library from the Workspace

Description

The lib_unload function unloads a data library from the workspace environment. The unload function does not delete the data or remove the library. It simply removes the data frames from working memory. By default, the lib_unload function will also synchronize the data in working memory with the data stored in the library list, as these two instances can become out of sync if you change the data in working memory.

Usage

lib_unload(x, sync = TRUE, name = NULL)

Arguments

x

The data library to unload.

sync

Whether to sync the workspace with the library list before it is unloaded. Default is TRUE. If you want to unload the workspace without saving the workspace data, set this parameter to FALSE.

name

The name of the library to unload, if the name is different than the variable name. Used internally.

Value

The unloaded data library.
