Remove rows with specific row numbers using dplyr's pipe function

I am looking for some way to delete specific rows by row numbers using dplyr's pipe function

library(dplyr)
head(mtcars)

Now let say I want remove row numbers c(1, 4, 7). Typically we would use mtcars[-c(1, 4, 7), ] to do the same.

However I want to use pipe to do the same.

Is there any way to do this?

Any pointer will be highly appreciated.

We can use slice

library(dplyr)
mtcars %>%
   slice(-c(1, 4, 7))

Or if we want to use [

mtcars %>%
      `[`(-c(1, 4, 7),)

Or use extract from magrittr

library(magrittr)
mtcars %>%
    extract(-c(1, 4, 7),)

We could use filter

library(dplyr)

# vector for rows to remove
to_remove <- c(1, 4, 7)

mtcars %>%
  filter(!row_number() %in% to_remove)
