How to access elements of sorted list in R

Question

I have the result of the sort function in R as the following: walk 23, facebook 21, news 20, net 17 Here it is showing every words with its corresponding frequencies. Suppose "sortList" is the variable name, and I am able to access the "facebook"'s frequency(23) by sortList[[1]]. How can I access the text "facebook"?

Answer 1

Double brackets access the data in a specific list element (see The difference between bracket [ ] and double bracket [[ ]] for accessing the elements of a list or dataframe)
But if you are dealing with a named list e.g.

sortList = list(walk=23, facebook=21, news=20, net=17)

It's as easy as

sortList["facebook"]
$facebook
[1] 21

or to access the names the names() function.

names(sortList)
[1] "walk"     "facebook" "news"     "net"
