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, standard_eval = FALSE)The library to copy.
The variable name to hold the new library.
The parameter will assume non-standard
(unquoted) evaluation unless the standard_eval parameter is set
to TRUE.
The path to copy the library to.
A TRUE or FALSE value which indicates whether to
use standard (quoted) or non-standard (unquoted) evaluation on the
nm parameter. Default is FALSE. Use this parameter if you want to
pass the target library name in a variable.
The new library.
