The lib_copy function copies a data library. The function accepts a library and a destination path. If the destination path does not exist, the function will attempt to create it.

Note that the copy will result in the current data in memory written to the new destination directory. If the library is loaded into the workspace, the workspace version will be considered the most current version, and that is the version that will be copied.

lib_copy(x, nm, directory_path)



The library to copy.


The unquoted variable name to hold the new library.


The path to copy the library to.


The new library.
