[R] help in a separate window under linux

None of these "pager" things work right. No matter what I set up, if I type
a window opens and the object structure is shown. This can certainly be useful
when transferring data, but it's not usually what I want. I would like to see
the data in a table format, similar to what "print" does but in a separate,
scrollable window, more like what S does.
