If a computation blocks R and doesn't allow it to process events, then R cannot respond to user requests. My guess would be that justGCRMA calls some C code that fails to let R process events periodically, so R.app can't do anything about it since R is single-threaded :/. Finder will know about R once the computation is done, so just let it finish (and in the meantime bug the author of the code to let R process events ;)).
