I want use column's name in mutate function as following:
data = data.frame(x = 1:3, y = 3:1)
data %>% mutate(across(everything() , .fns =list( i_dont_know_what ) , .names = "m_{col}"))
Result:
x y m_x m_y
1 1 3 x y
2 2 2 x y
3 3 1 x y
It would be cur_column()
library(dplyr)
data %>%
mutate(across(everything() , ~ cur_column(),
.names = "m_{.col}"))
-output
x y m_x m_y
1 1 3 x y
2 2 2 x y
3 3 1 x y
