I have a list in R some 10,000 elements long. Say I want to select only elements, 5, 7, and 9. I'm not sure how I would do that without a for loop.
I want to do something like
mylist[c(5,7,9)] should do it.
You want the sublists returned as sublists of the result list; you don't use [] (or rather, the function is
[[) for that -- as Dason mentions in comments,
[[ grabs the element.
