[R] Appearance of Forest Plot

[Joshua Wiley]

Hi,

Thanks for the example!  What about plotting it to pdf (or you can use
your favorite file format, just switch png(), jpeg(), bmp(), tiff()
for the pdf() call)?

pdf(file = "temp.pdf", width = 14, height = 38)
forest (metaeg,byvar=year)
dev.off()

I attached the PDF result so you could look at it.  As far as I can
tell, forest() does not mess with the par() settings too much, but
slightly resizing things/fiddling with margins did not give me nearly
what I would need to fit something that big on a screen.  From a PDF
or some graphics format though, it is easy to zoom in or out until the
image fits.  An alternative might be to break up the one big plot into
2-3 smaller ones.

Cheers,

Josh
