Dear list members, Does anyone know how to use rm() to remove only variables but not declared functions from the environment ? I understand I could name all the functions with, let's say "f_something", make sure that all variables do not start with "f_" and then remove all BUT objects starting with "f_". However, I have already defined all the functions and it would be troublesome to change all of them to a new name. Any hint ? Thanks Paulo Gustavo Grahl, CFA
