R help - Aug 2004 - Drawing multiple plots on one page for publication.

Hi All,

I have been using R for a while but only recently tried to draw quality plots
for publications.  I spent a few days tried to figure out how to draw multiple
plots on a single page to a postscript or pdf file but not successful.  The
drawing is perfect OK if it is displayed on the screen using x11() device.  
E.g.

x11()
par(mfrow=c(2,2))
par(mai=c(0.5,0.3, 0.6, 0.4))

plot(x, y, ..........)
plot(x, z ...........)
plot(z, y,...........)
plot(z+x, x-y, .....)

Four plots displayed on the screen when X-Win32 was set up.  Please advice how
can I save this to a postscript or PDF file or any kind of file for publication
and powerpoint slide?

Thank a lot..

Zach,

try:


pdf("Name.pdf")
par(mfrow=c(2,2))
par(mai=c(0.5,0.3, 0.6, 0.4))

plot(x, y, ..........)
plot(x, z ...........)
plot(z, y,...........)
plot(z+x, x-y, .....)
dev.off()

Just replace `x11()' by `postscript()' or `pdf()': you may want to
set the
width, height and pointsize suitably.

[You can use dev.copy2eps to copy the screen, but for publication-quality 
plots should should replot on the desired end device to use the correct 
font metrics.]
