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. Regards, - Robert http://www.cwelug.org/downloads Help others get OpenSource software.

You could transfer the data to MacAnova and do it there. There is an example here: http://tolstoy.newcastle.edu.au/R/help/03b/7504.html Type help in MacAnova to get info on other graphics functions.

Than, R will show you nice graphics even if run remotely.>For example, with gnuplot I can do the following: > echo 'set terminal dumb ; plot sin(x)' | gnuplot >to generate a simple sin wave. Regards,Amusing for me that you mention this: I wrote that code, many years ago. Despite gnuplot was aiming higher graphic output quality on average, my contribution was readily accepted, and considered useful. While it is possible to attach images within an email, rough graphics is sometimes simpler and sufficient. I do not know how easy (or not) it would be writing a dumb device for R, but I wish that if someone ever contributes it, it will be accepted by the core team. -- Fran?ois Pinard http://pinard.progiciels-bpi.ca
This may not help, but if you have S-Plus on the machine you're connecting to, it has a printer() device for this sort of thing.

I last used such plots ca 1985, long before R was conceived of and when student terminal rooms had 80*24 VDUs.> I'd like to do some simple XY plots in R with the output in text > (ascii).

I even see people using Windows Terminal Services remotely over quite slow lines.> I've looked at ?plot, ?par, and ?plot.default but didn't see anything > obvious.You need to look at devices (e.g. ?Devices), not how to plot on a device. BTW, devices do not need to be part of R so anyone could write such a device and contribute it (in a package). -- Brian D.

There are some very basic interface functions to gnuplot in the
TeachingDemos package that may make option 2 below a little quicker. Or
even better you could expand them to work better.
The following works on a single windows machine (don't have linux or a
remote machine to test with):
library(TeachingDemos)
x <- runif(100)
y <- rnorm(100)
gp.open()
gp.send('set terminal dumb')
gp.plot(x,y)
# switch to gnuplot window to look at plot
gp.close()
Hope this helps,

From the responses so far, the short answer appears to be, no.
That appears to leave two options for viewing plots on a remote machine:
1) use X11 forwarding (requires an X11 server and that X11 forwarding be
enabled), although the plots won't be in text.
2) output the data to a file and use another program to plot the data as

Is that a fair summary?
