How do you bite rowwise?

I'm trying to bite() based on start (X7) and end(X8) columns but I cannot figure it out.

Hmm, since it's a data frame (perhaps a tibble, given the headers), I don't have any better idea than using dplyr and its rowwise():

library(dplyr)
data %>%
  rowwise() %>%
  mutate(sq_sub = bite(sq, seq(X7, X8))) %>%
  # optional
  ungroup()

Currently on the phone and away from any computer, so I cannot confirm whether it's working, hopefully me or Dominik can valisate it soon.

Side note, good to know that extracting a subsequence given by start and end indices is something people do, we were thinking of a function optimized for exactly this use case.

Thanks Laura, did not work. bite() is really sensitive! and returns "it's not implemented for this type of object".
