[R] text plots?

[Robert Citek]

Is there a way to do text plots in R?

I'd like to do some simple XY plots in R with the output in text  
(ascii).  For example, with gnuplot I can do the following:

echo 'set terminal dumb ; plot sin(x)' | gnuplot

To generate a simple sin wave.  Since I connect to a remote Linux  
machine using SSH, being able to generate a rough idea of what a plot  
will look like in text would be of benefit.  I've looked at ?plot, ? 
par, and ?plot.default but didn't see anything obvious.
