R help - Aug 2004 - Question from Newbie on PostScript and Multiple Plots

Hi,
 
As I'm pretty new to R I hope this question isn't too basic.  
 
I am currently looping through my dataset and for each iteration am
producing three separate plots.  When I output these plots to the screen
they are nicely grouped as three plots per page, however, when I try to send
it to a PostScript file I get one page for each plot.  I have adjusted my
postscript options so that my plots are the size that I want and the paper
is set to portrait, I just can't figure out how to get all three plots on
one page in the postscript file.  I've been through the archives on the list
(albeit not exhaustively) and the manuals available on the R site and cannot
figure out how to solve my problem.
 
Thanks,
-Heather

Either one of the following work for me:

# Do 3 plots in a 2 x 2 matrix
postscript(file = "ThreePlots.ps", horizontal = FALSE)
par(mfrow = c(2, 2))
plot(1:5)
barplot(1:5)
boxplot(rnorm(10))
dev.off()

# Do 3 x 1
postscript(file = "ThreePlots.ps", horizontal = FALSE)
par(mfrow = c(3, 1))
plot(1:5)
barplot(1:5)
boxplot(rnorm(10))
dev.off()

Can you provide an example of the code that you are using?

Have you looked at ?par("mfrow") ?

Hi,

As I'm pretty new to R I hope this question isn't too basic.

I am currently looping through my dataset and for each iteration am
producing three separate plots.  When I output these plots to the screen
they are nicely grouped as three plots per page, however, when I try to 
send
it to a PostScript file I get one page for each plot.  I have adjusted my
postscript options so that my plots are the size that I want and the paper
is set to portrait, I just can't figure out how to get all three plots on
one page in the postscript file.  I've been through the archives on the 
list
(albeit not exhaustively) and the manuals available on the R site and 
cannot
figure out how to solve my problem.

Thanks,

PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Marc and Partha,

Thank you both for your suggestions of using par("mfrow"), that's
exactly
what I needed to do.  In fact I already had it in the code (which I didn't
write originally) and simply had to put my postscript statement in front of
it. :)

It works great now!  Thanks for the quick responses.

Heather

Either one of the following work for me:

# Do 3 plots in a 2 x 2 matrix
postscript(file = "ThreePlots.ps", horizontal = FALSE) par(mfrow =
c(2, 2))
plot(1:5)
barplot(1:5)
boxplot(rnorm(10))
dev.off()

# Do 3 x 1
postscript(file = "ThreePlots.ps", horizontal = FALSE) par(mfrow =
c(3, 1))
plot(1:5)
barplot(1:5)
boxplot(rnorm(10))
dev.off()
