I think this is what you want. Notice the use of 'list' in the rep to create a list of list:
> fred <- list(happy = 1:10, name = "squash") > x <- rep(list(fred), 5) > str(x) List of 5 $ :List of 2 ..$ happy: int [1:10] 1 2 3 4 5 6 7 8 9 10 ..$ name : chr "squash" $ :List of 2 ..$ happy: int [1:10] 1 2 3 4 5 6 7 8 9 10 ..$ name : chr "squash" $ :List of 2 ..$ happy: int [1:10] 1 2 3 4 5 6 7 8 9 10 ..$ name : chr "squash" $ :List of 2 ..$ happy: int [1:10] 1 2 3 4 5 6 7 8 9 10 ..$ name : chr "squash" $ :List of 2 ..$ happy: int [1:10] 1 2 3 4 5 6 7 8 9 10 ..$ name : chr "squash" > x[[1]]$happy[5] [1] 5 > On Tue, Sep 14, 2010 at 9:29 AM, Alaios <ala...@yahoo.com> wrote: > I would like to thank you very much all that you helped me so far. > So I tried to check how the following works > > fred <- list(happy = 1:10, name = "squash") > rep(fred, 5) > > This returns the following : > >> fred[1] > $happy > [1] 1 2 3 4 5 6 7 8 9 10 > > >> fred[2] > $name > [1] "squash" > > What I am trying to do is to address the number 5 of the fred[1] $happy value. > I tried something like fred[1][5] fred[1,5] > but it didn't work > > I would like to thank you in advance for your help > > Best Regards > Alex > > > > > ________________________________ > From: Dennis Murphy <djmu...@gmail.com> > > Cc: Rhelp <r-help@r-project.org> > Sent: Tue, September 14, 2010 3:13:37 PM > Subject: Re: [R] Object oriented programming in R. > > Hi: > > You could create a list of lists, where the outer list would be between agents > and the inner list within agents.
