R help - Oct 2008 - extracting a subset of sublists form a list; vectorized form

Hello;
I'll put my real problem through a simple example:
I've got a main list:
> main.lst <- lst()
With a number of sublists:
> for(i in 1:1000){
   main.lst[[i]] <- list()
   main.lst[[i]]$first  <- runif(1,0,1)
   main.lst[[i]]$second <- runif(2,3,4)
  }

If later on I need to split this list, how could I extract several
sublists in a vectorized form? For example, to extract the four first
sublists, to be passed to a function, sintaxis like this won't work:
> sublist <- main.lst[[1:4]]
Although I could do
> sublist <- list()
> for(i in 1:4){ sublist[[i]] <- main.lst[[i]] }
I would hope that a vectorized way could exist.

Thanks, and regards,
Javier

Dear Javier,
> sublists, to be passed to a function, sintaxis like this won't work:
> 
>> sublist <- main.lst[[1:4]]
are you looking for:
sublist <- main.lst[1:4]
