[R] loading saved files with objects in same names

An alternative that I have been advocating is using

  attach("A.RData")

etc. It does something similar as the above, but more
conveniently:
It loads the objects into a new environment  *and* attaches that
environment to your search()  path, so you can access them
directly, but attach() will never accidentally destroy existing
R objects in your global environment ( = search()[[1]] ).
