R help - Feb 2008 - Drawing several pictures on a plot

Hi,

I want to draw several pictures on one plot and do as follows:

xy<-matrix(rnorm(100,100,10),50)
op <- par(mfrow = c(2, 2), pty = "s")
plot(xy,ann=F);plot(xy,ann=F);plot(xy,ann=F);plot(xy,ann=F)
par(op)

What I need now is to set the size of the pictures within this plot
since there is too much free space among the pictures, making the plot
look not that pretty. How can I do that?

Thanks,
Marcin

The empty space is the margins around the plot.  The par function is
used to set the size of the margins using either mar or mai arguments.
Setting this to a smaller set of values will give your individual plots
more space.  You may also want to look at the oma argument to set an
outer margin (for overall titles/labels).

See ?par for the details.

Hope this helps,

Hi Marcin,

in addition to Greg Snow's answer, you may also check the "Introduction
to R" Manual, especially Section 12.5. In subsection 12.5.3 (in the PDF 
version), there is also a graphical example of the margins.

Mam nadzieje, ze to pomoze.

Do widzenia,
Roland
