mv: Rename an Object in the Workspace

In mrdwab/mrdwabmisc: Miscellaneous R functions, mostly for data processing

Description

Renames an object in the workspace, "removing" the orinal object. This does so without creating a copy of the original object. If an object in the workspace currently exists with the new name specified, the function prompts the user to verify that they want to overwrite that object before proceeding.

Usage

mv(currentName, newName)

Arguments

currentName	The current name of the object
newName	The new name for the object

A good amount of discussion on when R makes a copy in memory in this discussion thread: https://stat.ethz.ch/pipermail/r-help/2008-March/156028.html.

Examples

x <- runif(1e7)
ls()
x.add <- tracemem(x)
mv(x, y)
identical(x.add, tracemem(y))
ls()
