[R] figure with inset

[Gregory Snow]

There is a subplot command in the latest version of the TeachingDemos
package (version 1.1 available today) that does what you want using
traditional graphics (others have given suggestions using grid
graphics).  An example:

> x <- 0:10
> y <- x^4
> plot(x,y,xaxs='i',yaxs='i')
> subplot( plot(x,y,xaxs='i',yaxs='i',xlab='',ylab=''),
c(1,5),c(5000,9000))

Or

> tmp <- cnvrt.coords(x=c(.1,.5),c(.5,.9),input='plt')$usr
> subplot( plot(x,y,xaxs='i',yaxs='i',xlab='',ylab=''), tmp)

Or

> subplot( plot(x,y), 1,9000, hadj=0, vadj=1)


See the help on subplot for more examples.
