I know I can use ls() and rm() to see and remove objects that exist in my environment.

However, when dealing with "old" .RData file, one needs to sometimes pick an environment a part to find what to keep and what to leave out.

What I would like to do, is to have a GUI like interface to allow me to see the objects, sort them (for example, by there size), and remove the ones I don't need (for example, by a check-box interface). Since I imagine such a system is not currently implemented in R, what ways do exist? What do you use for cleaning old .RData files?

Thanks,

Tal
