You could always use Splus version 3. It had a crt() and a printer()
graphics device, which produced ascii plots. I'd paste an example here
but doubtless the widespread use of proportional fonts would make it
look like what we used to call 'line noise' back in the old days.
It can do simple line and point plots, but dont expect too much:

Error in image.default(matrix(runif(100), 10, 10)): Inactive device or
unimplemented device primitive

For those of you with proportional fonts, here's 10 data points with a
fitted linear model:

Since R is open source, if you really really want this, you could
either write a 'crt()' graphics device for R, or if you really really
really want it, pay someone to do it!
