我想使用 dplyr :: rename()



<$ p重命名列$ p> df%>%
重命名(subject = Subject,
code = Cat Nbr,
title = title,
mode =模式!)

但是我收到一个错误:意外符号: / code>



如何调和?

解决方案

p>要引用包含非标准字符或以数字开头的变量,请将名称换成后面的勾号,例如`Instruction..Mode!`


I have table with difficult headers like this:

  Subject  Cat Nbr  Title       Instruction..Mode!
1 XYZ      101      Intro I     ONLINE
2 XYZ      102      Intro II    CAMPUS
3 XYZ      135      Advanced    CAMPUS

I would like to rename the columns with dplyr::rename()

df %>%
 rename(subject = Subject, 
        code = Cat Nbr, 
        title = title, 
        mode = Instruction..Mode!)

But I am getting an Error: unexpected symbol in:

How might I reconcile this?

解决方案

To refer to variables that contain non-standard characters or start with a number, wrap the name in back ticks, e.g., `Instruction..Mode!`
