Here is an example list of data. You would access it by: x[[day]][[hour]]
instead of how you mentioned in your email. > # create a list of 3 days and 3 hours to show how the list would look > set.seed(1) > x <- vector('list', 3) # top level is day > for (day in 1:3){ + for (hour in 1:3){ # create list of random lengths + x[[day]][[hour]] <- list(floor(runif(runif(1, 1, 10), 1, 20))) + } + } > # output the list as you might have constructed it > dput(x) list(list(list(c(8, 11, 18)), list(c(18, 18)), list(c(12, 2, 4, 4, 14, 8))), list(list(c(10, 14, 19, 8, 15, 18, 5)), list( c(3, 6, 8, 1, 8, 17)), list(c(10, 12, 10, 4))), list(list( c(13, 16, 3, 14, 8, 16, 13, 15)), list(c(11, 15, 1, 10, 14 )), list(c(10, 17, 9, 5, 2, 2, 7)))) > > #access the 2nd day, third hour > x[[2]][[3]] [[1]] [1] 10 12 10 4 On Sat, May 8, 2010 at 2:24 AM, Remi SoftR <remir...@gmail.com> wrote: > Dear all, > > d, d=1,...,10 is a day, h, h=1,...,24 is an hour and tt_dh(1),tt_dh(2),... > is the arrival time of the 1st, 2nd etc client on day d during hour h.
