# cheapr (Development version)

* New function `na_insert` to randomly insert `NA` values into a vector.

* New function `vector_length` as a hybrid between `length` and `nrow`.

* Limited support added for 'integer64' objects. This applies to the
`NA` related functions as well as the GCD and LCM functions.

#' `sample_()` is an alternative to `sample()` that natively samples

#' `na_insert` inserts `NA` values randomly into your vector.
#' Useful for generating missing data. \cr
#' `vector_length` behaves mostly like `NROW()` except
