R 如何從數據框列中刪除特殊字符 ’？

Question

使用 tidyverse 我想從“教育”列中刪除特殊字符，以便它只說碩士或學士。 由於我使用的是 Tidyverse，我想舉例說明使用管道並保持數據框不變：

library(tidyverse)
education <- data.frame(Education = c("Master’s ","Professional ","Bachelor’s"))
education <- sapply(education,str_replace(education,"’",""))

Answer 1

這就是正則表達式的用途：

gsub("[^A-Za-z]", "", c("Master’s ","Professional ","Bachelor’s"))

產生：

[1] "Masters"      "Professional" "Bachelors"   

Answer 2

使用dplyr

data.frame(Education = c("Master’s ","Professional ","Bachelor’s")) %>% 
   mutate(Education = str_replace(Education,"’",""))
      Education
1      Masters 
2 Professional 
3     Bachelors
