如何从R中的字符变量中删除一组单词？

Question

我有一个带有如下角色变量的数据集，我想从该变量中删除一些单词。

我的数据：

   <VirtualHost *:80>
    ...
    ServerName BBB
    ...
   </VirtualHost>

我想删除变量中的一些单词和字母。

预期结果：

   variable
 1 "star war it ik ar"
 2 "jammu kashmir DO"
 3 "hey Ho dude"
 4 "time kya hi abhi"
 5 "every one ji"
 6 "thanks to iF everyone"
 7 "hey i am in america yo"

我尝试了以下内容：

   variable                 created_var
 1 "star war it ik ar"      "star war"
 2 "jammu kashmir DO"       "jammu kashmir"
 3 "hey Ho dude"            "hey dude"
 4 "time kya hi abhi"       "time kya abhi"
 5 "every one ji"           "every one"
 6 "thanks to iF everyone"  "thanks to everyone"
 7 "hey i am in america yo" "hey i am in america"  

上面的代码适用于单个单词，但不适用于单词组。如何删除waste <- c("it", "ik", "ar", "DO", "Ho", "hi", "iF", "yo") data$created_var <- gsub(waste, "", data$variable) 中的所有字词？
