Sort a named list in R

I have a named list of term frequencies,

> list
$`in the`
[1] 67504

$`to the`
[1] 36666

$`of the`
[1] 79665

$`on the`
[1] 31261

$`to be`
[1] 25862

$`for the`
[1] 28332

I want to sort them into descending order according to the frequencies. How to do this? I tried sort, sort.list, order but had errors saying they don't accept this type of list.

If the list is large and involves large objects, would it be better to just use names?

 lst = lst[order(names(lst))]

You can try by unlist and then use order

lst[order(unlist(lst),decreasing=TRUE)]
#  $`4`
#[1] 9

#$`3`
#[1] 7

#$`1`
#[1] 5

#$`2`
#[1] 4

#$`5`
#[1] 2

data

lst <- setNames(list(5,4,7,9,2),1:5)
