parent.frame() will give you the frame of the caller. For example, in the browser, caller <- parent.frame() ls(caller) caller$foo etc. parent.frame() has an arg specifying how far up the stack you want to go. There's also the browser() command "where" which shows you the calling stack, to tell you what to pass to parent.frame. Duncan Murdoch
