Hi Joseph, Without a reproducible example, you probably will not get the precise code for a solution but look at ?list
Rather than doing what you are doing now, put everything into a list, and then you will not need to use get() at all. You will just work with the whole list. It can take a bit to get to get used to working that way, but it is worth it.
