R help - Jul 2012 - Assigning a new name to object loaded with "load()"

I would like to load a binary file into R using load(), and then assign a new
name to it, regardless of the name it was saved under. Can you please
provide a code sample? Thank you!

Here is one way.  You seem to assume that the save file contains
exactly one object and this function makes the same assumption:
theObjectSavedIn <- function(saveFile) {
     env <- new.env()
     load(saveFile, envir=env)
     loadedObjects <- objects(env, all=TRUE)
     stopifnot(length(loadedObjects)==1)
     env[[loadedObjects]]
 }

Use it as
> tfile <- tempfile()
> myObj <- 101:107
> save(myObj, file=tfile)
> savedObj <- theObjectSavedIn(tfile)
> savedObj
[1] 101 102 103 104 105 106 107

Ummm,  what is the antecedent of the pronoun "it" in the forgoing?

The structure of your sentence makes it sound like "it" refers to
***the binary file*** --- but I don't believe that's what you mean.

If you by "it" you mean an object (the object? one of the objects?) in
the saved binary file, then something like:

     y <- x
     rm(x)

should do what you want.

Distinguish the container from the thing(s) contained.
