[OGRUG] Putting two figures together in R

[Robert Biddle]

I'm not 100% sure I know what you want, but if it's just to have
two plots in the same image side by side, I do this all the time using 
par and mfrow.
A simple example would go like this:

 > par(mfrow=c(1,2))
 > hist(runif(100))
 > boxplot(runif(100))
 > par(mfrow=c(1,1))

That gives an image with a histogram on the left and a boxplot on the right.
You can vary the mfrow numbers as you wish to have them in a row, a 
column, or a grid.
The c(1,1) setting at the end is just to change back to a single plot.

Anyway, when it looks right, then you can just save the window to a file.
For data and graphs I tinker with a lot, I normally embed this kind of 
thing within a call to pdf or png to
both display the images and save them to a file.

Anyway, I hope this helps.
Cheers
