R help - Jun 2004 - use of split.screen() with postscript device

Greetings,

I am new to R and quite confused by the apparent inconsistency in it's 
behavior. My latest difficulty lies in producing eps output for use with 
latex. In particular, I was successful in obtaining a single figure by using:

postscript("ripple1.eps",onefile=FALSE)
plot(nu_set[[1]],ip[[1]])
lines(nu_set[[1]],predict(fitIp[[1]]))
dev.off()

...but then I tried to place two figures on the same output sheet by using 
split.screen() as follows:

postscript("ripple1.eps",onefile=FALSE)
split.screen(c(1,2))
screen(1)
plot(nu_set[[1]],ip[[1]])
lines(nu_set[[1]],predict(fitIp[[1]]))
screen(2)
plot(rangeIpNorm)
dev.off()

and received no output whatsoever. Furthermore, I can no longer get postscript 
output using the original commands! I've tried exiting and re-starting R,
and
am just about to reboot because I almost cannot believe what I am seeing.

Can you spot anything that I am doing wrong?

Thanks & Best Regards,
Steve

Hi!

par(mfrow=c(2,1))
splits the plot in two parts for example.
For more information about graphics read introduction to R
provided with your R installation.
if par(mfrow ...
par(mfcol is not flexible enough for you
you can examine the documentation for

?layout

If you need even more flexibility
look at the grid package of Paul Murrel

There is also an artikle in Rnews about combining the graphics function in the
graphics package from P. Murrel.

You may also to consider to learn the graphic functions in the lattice package
of by Deepayan Sarkar
which build on grid.

Sincerely
Eryk
