[R] Simple network diagram

[Rainer Hahnekamp]

Hello,

I'm trying to create a simple network diagram like that on 
http://www.pauck.de/marco/photo/infrared/comparison_of_films/diagram3.gif. 
Unfortunately I've not yet found any function that could do this.

I think this should not be a difficult task since I only need two 
vectors and perhaps the names of the dimensions as data source.

Could somebody help me please?

Greetings,
-Rainer
