Hello R-Community

I did a lot of research, but i found no answer for my issue.

I try to plot multiple Plots. I do this with the layout() function.
The following two pictures show the defined layout:

http://www.stuber.info/layout_2.jpg

The final plots looks like:
http://www.stuber.info/plot_1.jpg
http://www.stuber.info/plot_2.jpg


So far is all right. Now my problem is, that I'm not able to make the borders as needed. See the layout_1.jpg and layout_2.jpg again. The colored lines represents the needed borders.
I tried to draw lines into every plot to bulit a global border. But it's a hack job and it's "ugly". I also tried to make the layout with the par() or the split.screen() functions, but without success. To interleave layouts is also not possible in R (or does anybody know a way to do it?)

Does anyone can help me with this issue?
