在R中对命名列表进行排序 [英] Sort a named list in R

问题描述

我有一个术语频率的命名列表，

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

我想根据频率将它们降序排列.这该怎么做?我尝试了 sort，sort.list，order ，但是有错误提示他们不接受这种类型的列表.

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.

推荐答案

您可以按unlist尝试，然后使用order

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

数据

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