First, you will need a place to put it -- an "outer" margin.
You can set this up with:

	par(mfrow = c(2, 6), oma = c(0, 0, 2, 0))

This sets up an outer margin with 2 lines of text at the top of the plot.

Now, you do your plots and add the title with

	mtext("Your Overall Title", line = 0.5, outer = TRUE)

This puts the title in the center of the top margin, 0.5 lines out from
the plot.

With large arrays of plots like this you will get lots of blank space
on the page, so you may want to play with shrinking the margins around
the individual plots.  Probably something like:

	par(mfrow = c(2, 6),
	    oma = c(0, 0, 2, 0),
	    mar = c(5.1, 4.1, 2.1, 2.1)

This eliminates at lot of the space at the top of the individual plots.

I'll defer to "historians" on these ones.  (I agree that being
able to
save the current history in a file would be a good idea).

Could you figure out how to tell us your platform and R version, please?

On Windows, yes (called savehistory).
Should be easy to add on Unix (non-GNOME).

On Windows, 16K chars or  512 lines, in consolestructs.h 

On Unix (non-GNOME), 512 lines, in src/unix/system.c. Can be overriden by
the environment variable R_HISTSIZE.

GNOME: ditto, in file src/unix/gnome/system.c

And while we're at it: just printing the current history would be a
nice thing to have (like bash's history command).

Hello everyone,

I had a few questions that I have not been able to figure out despite a lot of
reading.



1) Adding a title to a multiplot figure:

If I plot multiple plots with 
>par(mfrow=c(2,6))
how do I add an overall title to the figure, not the individual plots?




2) Saving histories on the fly:

Is there a .Rhistory equivalent to
>save.image()
? I would like to be able to save the .RData and .Rhistory files and move to
another machine. Right now I have to quit R which looses the plots I am working
on.




3) Setting the size .Rhistory:

What is the maximum size of .Rhistory and where is it set?



Thanks in advance for any replys,
