Hi, ~ well that seems to be a better solution. Question is how much an enviroment for each node costs in terms of save space..
Seems unlike that it would expand you space very much. Every function you create will have an environment.
The example code is hard to present, because it is really based on that problem. The frame of the problem is, that I have to write a program that gives each node in a binomial tree a function with individual parameters.. in my case the current stock price at that node. I don't want to create these functions manually.. that would be too much of an overload with a tree even of moderate size. But if I define these functions via the as.function functionality it gives me the above problem.
You need to demonstrate what "tree" structure you propose to populate and then access. Since tree's are not an R data type, you should show us _exactly_ how you will create one, presumably using "lists". Once you have a small example it is very easy to present by using the output of the 'dput' function.

You should also realize that you are probably limiting your audience severely by not posting context. Most people do not read Rhelp on Nabble.
