[R] how to check object size in workspace

[Weiwei Shi]

hi,

I tried to keep my workspace as small as possible when i tried to
save.image(). Sometimes, I am not sure whether obj in workspace will
be needed in future or not. However, I want to delete some "big" ones
when I use save.image(). BTW, I know I could use "save", but I would
like to know : how to check objects' size (the size when I try to save
it in disk) in workspace, anyway.

thanks,
