R 从字符串中删除特定短语

我试图利用R进行一些基本的文本分析

我有一个包含复杂数据类型的列。我希望维护一个单独的表，可以使用该表从第一个数据列中删除某些短语

我尝试过gsubfn，但没有成功

比如说

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT","BODY CORPORATE")

试试这个

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT | BODY CORPORATE")
x <- gsub(removefields, "", dirtydata)

---

dirtydata这概括了您在
removefields
中输入的内容，并在要删除的字符串周围去除空格：

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <- c("COURT","BODY CORPORATE")
removefields <- paste0("\\s+", removefields, "\\s+", collapse = "|")
x <- gsub(removefields, "", dirtydata)

dirtydata我们可以使用
tm
package

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT","BODY CORPORATE")

library(tm)
removeWords(dirtydata, removefields)

> removeWords(dirtydata, removefields)
[1] "JOHN "   "@PETER"  "BOB 22"  "RUPERT "

dirtydata请使用R的
base
函数查找下面编辑的代码

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT","BODY CORPORATE")
pastedFields = paste0(removefields,collapse = "|")
gsub(pastedFields,"",dirtydata)

dirtydata请包含其他加载包的名称。但是您可以尝试
gsub（粘贴（removefields，collapse=“|”），“，dirtydata）
可能的重复项，或者您可以对其进行详细说明吗？我假设你们得到的是列表格式的输出，除了向量？如果是这样的话，请将您应用代码的代码行放在您的数据列上
dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT","BODY CORPORATE")

library(tm)
removeWords(dirtydata, removefields)

> removeWords(dirtydata, removefields)
[1] "JOHN "   "@PETER"  "BOB 22"  "RUPERT "

dirtydata <- c("JOHN COURT","@PETER","BOB 22","RUPERT BODY CORPORATE")
removefields <-c("COURT","BODY CORPORATE")
pastedFields = paste0(removefields,collapse = "|")
gsub(pastedFields,"",dirtydata)
