Yes, and you *are *using an interface with menus and a toolbar and you can
select things with the mouse ...  In short, a Graphical User Interface,
albeit a simple one.  It contrasts with Rterm, in Windows' parlance a
console application (a pure-text interface).

R is not a clone of S-PLUS, and does not have a user-programmable GUI
under Windows.  There are ways to program interfaces, but none as easy to
program as the Axum-based front-end of S-PLUS for Windows. Look at the
tcltk package and its demos for the simplest approach.

If you want the features of S-PLUS, please use it.

Correct. There is currently no dynamic graphics in R.  If you install
package xgobi from CRAN it will show some results (but do read all its
prerequisites carefully).
