You may not - and for good reason, as the user may have an existing variable
called “name” that will be destroyed by such an action. If you run "R CMD
check —as-cran" on a package containing this code you will get a warning (or
maybe a note, I can’t remember), and the package would most likely be refused
if you tried to submit it to CRAN.
