You can get a list of all functions in your workspace with ls()[sapply(ls(), function(x) is.function(get(x)))] # or ls()[sapply(sapply(ls(), get), is.function)] Removing everything else is rm(list=ls()[sapply(ls(), function(x) !is.function(get(x)))]) # or rm(list=ls()[!sapply(sapply(ls(), get), is.function)]) That suffices if you don't have any names starting with .period; if you do, you'll need ls(all=TRUE) KK On Mon, Feb 2, 2009 at 3:16 PM, Paulo Grahl <pgrahl at gmail.com> wrote:
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
