How to rename factors in dplyr pipeline

tidyverse

I asked about method to rename factors and the selected answer uses fct_relabel on the factor vector only.

df$grp = df$grp %>% fct_relabel(str_replace, "_something", "")

But df in my usage is often the result from tidyr::gather and I don't feel like breaking the %>% pipe to name it just to do fct_relabel, and then resume the pipe. Any suggestions? Thanks!

How about this?
df <- df %>% mutate(grp = fct_relabel(grp, str_replace, "_something", "")) %>% ...

Thanks. So simple! I should have looked up how to input the argument from the help :-

fct_relabel(.f, .fun, ...)
