R help - Mar 2001 - Chart Size

Dear R People:

How do I change the size of the chart, please?

I tried changing the mar option in par, but that didn't 
do it.

I'd like to have a larger chart.

Thanks in advance.

R 1.1.1 on Windows  (I know....I'll update soon)

Sincerely,
Erin

Do you mean the version you save to disk or print out? Or the version you
see on the screen?

I'm not sure about the screen. To print the current plot
dev.print(height=6, width=6, horizontal=FALSE)
Vary the height and width to suit your taste.
You might want to include pointsize=20 or whatever so the text is in
proper proportion to the rest of your plot. (Unfortunately this will also
make the hash marks too big and put a big gap between the axis labels and
the axis title like this

----+----+----+----+----+---
    |    |    |    |    |
    |    |    |    |    |


    1    2    3    4    5




          axis title

(My own solution is to make the plot quite small, say 3 x 3, so that the
plot symbols, the axis lettering, and plot region are in proper
proportion. Then I scale up the postscript in the LaTeX document.)

This will certainly vary the proportion: margin/(plot region)

Open a graphics device using x11() or windows() or win.graph() and
specify height and width (in inches). E.g.:

        win.graph(width = 3, height = 5)

for a 3" X 5" window.

Try help(x11) for more info.
