在字符串中查找最常见的单词 [英] Find most common word in a character string

问题描述

我有一个字符串，需要找到字符串中出现频率最高的单词.我已经尝试了 max、which.max、sort、order 和 rank 的所有变体 我能想到的 - 但似乎无法正确计算出语法.我也尝试过这里找到的所有方法:计算频率出现在使用 R 的数组中

I have a character string and need to find the word in the string that occurs most frequently. I've tried every variation of max, which.max, sort, order, and rank that I can think of - but can't seem to get the syntax worked out correctly. I've also tried all of the methods found here: Calculate frequency of occurrence in an array using R

示例代码:

zzz <- c("jan", "feb", "jan", "mar", "mar", "jan", "feb") #random example data
zzz <- paste(zzz, collapse=" ") #make data look like what I'm working with
zzz
# [1] "jan feb jan mar mar jan feb"

在这个例子中，jan"出现频率最高.

I this example, "jan" occurs most frequently.

非常感谢任何建议！

推荐答案

这个怎么样:

Freq <- table(unlist(strsplit(zzz," ")))
# > Freq
# feb jan mar 
# 2   3   2 
> Freq[which.max(Freq)]
jan 
  3

如果您只想将实际单词作为输出，

If you just want the actual word as output,

> names(Freq)[which.max(Freq)]
[1] "jan"
