The "GUI" is the scrollable terminal window, multiple graphical devices,
and the menus (RGUI.EXE). There is also a "terminal" interface version
(RTERM.EXE) which is a text only application.

Those functions are not available in R but there is a package (tcltk)
which allows you to create 'buttons and boxes' style font-ends to
functions. This is pretty versatile and supports a wide range of
graphical widgets. I like this approach as TK is open source and cross-
platform. The tcltk package requires TCL/TK to be installed on your
machine.

I have not used S-PLUS for a long time but I am pretty sure that you
should be able to do most of what you want with the tcltk package.

Interaction with graphs is limited in R. I have seen it linked to XGOBI
and a GIS system doing some pretty dynamic stuff but, I think, getting
it all running together might be tricky.
