Usage
remove.packages(pkgs, lib = NULL)
Arguments
| pkgs |

Details
If the package was loaded via a previous call to library, then the package
is currently being used until it is unloaded. You must unload a package before you can
remove it.
Value
returns invisible
NULL.
- If the package is currently in use, returns a warning.
- If the package cannot be found, returns a warning.
Warning
Use this function with caution. Removing a package deletes it from the library (by default the directory TERR_HOME/library).
Differences Between TIBCO Enterprise Runtime for R and Open-Source R
- In R, the argument lib is given without the default NULL value.
- In R, this function does not display a
warning for the packages in use. No warning is given if the specified package is
not found in the specified library.
- In R, after the specified package(s) are removed, the HTML index of
packages is updated.
