How to add a suffix to a sequence of variables in R?
问题
你可以尝试这样修改代码来避免错误：
data <- data %>%
rename_at(vars(AGRA_A00_A09:AGRII_U80_U89), ~paste0(., "_cor"))
这应该能解决你遇到的错误。
英文:
My dataset has over 6k variables and I need to add a suffix to a sequence of variables, but not all of them. I'm trying:
data <- data %>%
rename_at(AGRA_A00_A09:AGRII_U80_U89, ~paste0(., "_cor"))
But I get the following error:
Error: object 'AGRA_A00_A09' not found
I've tried putting quote marks on the variables names and using across, but it still doesn't work. What am I doing wrong?

Close, use rename_with:
mtcars %>%
rename_with(disp:drat, .fn = ~ paste0(., "_cor")) %>%
head()
