[BUG] mutate() fails when using base R pipe (|>) instead of magrittr pipe (%>%)

[LaureTomas]

Hi, thanks a lot for maintaining plyranges — I really enjoy using it!

I just noticed a small inconsistency when trying out the new base R pipe. With %>% everything works fine, but when I switch to |> the code breaks specifically for mutate().

Here’s a minimal example:

library(plyranges)

ir1 <- data.frame(start = 2:6, width = 3:7) %>%
  as_iranges()

ir1 %>% 
  mutate(gc = width(.))

But with the base R pipe:

ir1 <- data.frame(start = 2:6, width = 3:7) |>
  as_iranges()

ir1 |> 
  mutate(gc = width(.))
Error in h(simpleError(msg, call)) : 
  error in evaluating the argument 'x' in selecting a method for function 'width': object '.' not found

I guess this might be related to how mutate() captures the . argument under %>%. Totally understand that supporting |> might introduce stricter R version requirements, but maybe there’s a workaround or at least a note in the docs to make this clear?

Thanks again for the great package!
