[R] Four quick questions

[Amy C. Peng]

I have four quick questions about R:

1)  Can R make a 3-dimensional rotating scatterplot?

2)  Does R have OLE capabilities?

3)  Is it possible to create a pop-up window in R to display a message and
allow for user input?  (I know I can use readline() from the command line,
but I just wondered if it was possible to use pop-up windows.)

4)  Once an RGui is opened, can I "send" a source file to the opened RGui
from outside the RGui (i.e., from a DOS command or something)?

I looked through the R documentation, and my guess is that the answer to
all four questions is "No", but I wanted to ask the "experts" to make sure
that I wasn't missing something!  Thanks for your help!

Sincerely,
Amy Peng
