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!

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!`
