You can fake it by doing 'R --save --restore --slave' which saves a
.Rdata file with stored functions and variables and restores whatever
one it can find.  There of course can be side effects if a workspace
exists from a previous use.

Oh, btw for getting tooltip help you can use this command and send the
output to a tooltip:

printf "?$TM_SELECTED_TEXT" | R --slave

Or when you said instant, did you intend mouse hovering to bring up
the tooltip?
