I find it hard to imagine you need to do it without using sapply. If you get over your phobia, you might like to try
sapply(v, "[", 3) If the elements of the list are all the same length, as in your example, you could do data.frame(v)[3, ] I think we need to know more about why you think you can't use sapply before we can really help you, though.

In particular, v=list(c(1,2,3,4,5),c(1,2,33,4,5),c(1,2,333,4,5),c(1,2,3333,4,5)) I want to access all the thirds items of the elements of the list. i.e., I want to access the elements, 3,33,333,3333. This can be done through sapply as: sapply(v,function(x) x[3]) But I need to access this without using 'sapply'. Like in a data frame, we do df[2,3] etc.... Any ideas?
