从 R 中的字符串向量中删除术语“list()”？

Question

我想知道如何从下面的字符串

Vector

中删除“list()”以获得我的

desired_output

？

Vector = c("Nc", "list(\"Year\")", "list(\"# of Treatments\")")

gsub("list","", Vector) # doesn't fully work

desired_output = c("Nc", "Year", "# of Treatments")

Answer 1

根据您的样本数据，您可以使用：

gsub("\"|\\\\|list\\(|\\)", "", Vector)

[1] "Nc"              "Year"            "# of Treatments"

它只是查找引号 (

\"

) 或反斜杠 (

\\\\

) 或

list(

或右括号 (

\\)

)
