Indexing list of data.frames – how to get all x-th columns?

Question

I have list of data.frames and I wonder whether there is an easy indexing way of getting all third columns of all data.frames. Or all columns named x? Speaking R:

Answer 1

Maybe this is somewhat easier:

lapply(mylist, "[[", 3)
lapply(mylist, "[[", name_of_column)
