[R] list()

Is anyone familiar with a good tutorial (in print or online) on the  
use of list()? I found Matlab structures to be a great way to pass  
complex variables (such as a model consisting of differently- 
dimensioned variables) back and forth between functions. It seems  
list() requires that you define the components within the command  
(model <- list( var1 =" ", var2 = " ", etc) and that if you don't  
fully define and name the component variables WITHIN the list command,  
you won't be able to refer to them by name elsewhere. Instead, you  
will have to remember the order and call the component variables as  
model[[1]] etc. instead of model$var1. Is this a correct  
understanding? Are there any good, comprehensive explanations on  
list() with examples?

Thanks!
