Hi Ottorino-Luca, I'm not sure how flexible the layout command is off the top of my head. I have never seen an example of what you describe using layout, so I will assume it can't be done.
One option is to use grid and lattice. This is possibly the best option if you are planning to do a lot of this sort of thing. Another option is to plot the second plot, on top of the first plot, using primitives such as points and lines, transforming your coordinates so that they match the coordinates of the first plot. This will be very difficult if you wish to put titles and axis on the nested plot, however simple if you restrict yourself to points and lines. Finding documentation and examples of R's graphical primitives should be easy. At the risk of sounding crude, I'm pretty sure both latex and many word processors allow one position one figure on top of another. This would seem the simplest solution for a one off job. Further to my post on R-devel, I recommend not using png format, except where absolutely necessary. regards -- Charlotte Maia http://sites.google.com/site/maiagx/home ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
