This entirely depends on the definition of "restricted", otherwise the 
answer is "yes".

You can't: R is free software. Well, of course you could build your own 
version of R that did not ship those functions. Anyway, typical 
restrictions are handled by settig permissions on the file system and/or 
arrange quotas for space / memory / CPU resources.
