I have several column names in my dataset (eat10.18) that have the suffix "_10p." I'd like to change that suffix to be "_p_10" but preserve the rest of the variable name. I only want this to affect columns that end in the exact string "_10p." I cannot figure out how to make this work with rename_with(). Can anyone help? Faux data below:

eat10.18 <- data.frame(id = c(1000, 1001, 1002),
eat_10 = c(2, 4, 1),
eat_10p = c(1, 2, 3),
run_10p = c(1, 1, 2)) 

In the above example, the variables "id" and "eat_10" would remain the same, but "eat_10p" and "run_10p" would become "eat_p_10" and "run_p_10"

Thanks for your help!

library(tidyverse)

eat10.18 %>%
  rename_with(~str_replace(.,'_10p$', '_p_10'))

    id eat_10 eat_p_10 run_p_10
1 1000      2        1        1
2 1001      4        2        1
3 1002      1        3        2

I suggest using gsub and referring to this post.

names(eat10.18) <- gsub(x = names(eat10.18), pattern = "_10p", replacement = "_p_10")

Result
