Is there a "move" command in R (equivalent of <- followed by rm)?
===

This is one of those "there has to be a function for this" questions.  It's not that big a deal, but it's just annoying enough that every time I rename an object I wonder if there's a better way.

Suppose I capitalize an object that I've created and realize I'd rather have it uncapitalized:

    # Create test data
    X <- runif(100)
    # Rename the object
    x <- X
    rm(X)

Is there a one-command way of doing this?  There are a few commands named `rename` in various packages but they all work on elements within a list, rather than on the list (or other object) itself.
