问题描述

我只想拥有

" Hi, this is a good time to start working together." 

两个单词之间只有一个空格.我应该如何在 R 中执行此操作?

Only one white space between two words. How should I do this in R?

推荐答案

gsub 是你的朋友:

test <- "Hi,  this is a   good  time to   start working   together."
gsub("\\s+"," ",test)
#[1] "Hi, this is a good time to start working together."

\\s+ 将匹配任何空格字符(空格、制表符等)或空格字符的重复，并将其替换为单个空格 " ".

\\s+ will match any space character (space, tab etc), or repeats of space characters, and will replace it with a single space " ".
