Hi, I have a list of 100, each list has 20 elements, and I would like to select the first 7 elements in each list. Let's take the alphabet as an example.
x <- lapply(1:100, function(i) sample(LETTERS)) I tried x[[1:7]], but it doesn't work. Can anyone enlighten me on how to do such selections? Thank you.
