R如何从数据框列中删除特殊字符？

Question

使用 tidyverse 我想从“教育”列中删除特殊字符，以便它只会显示硕士或学士。由于我使用的是 Tidyverse，因此我想举例说明使用管道并保持数据框不变：

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

Answer 1

这就是regular expressions 的用途：

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

产生：

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

Answer 2

dplyr

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