Hello, I would like to know whether R has a homogeneous function of S-plus's new.frame(), which create explicit frames in the evaluator and provide a locale for computations that can be shared among various functions. new.frame() in S-plus: http://www.uni-muenster.de/ZIV/Mitarbeiter/BennoSueselbeck/s-html/helpfiles/new.frame.html Thanks.
