your package vignette relies indirectly(*) on the codetools package, which is a package that is not guaranteed to be installed on all systems; it's only a recommended package. Because of this, R CMD check on you package fails on such systems (see below).
(*) Searching the code of your package for codetools gives zero hits, which suggests that it codetools is used by another package that your package depends on, but only as a soft dependency. Because of this, you need to declare codetools as a dependency in your package.
To fix this, please add codetools to Suggests:, i.e.
Suggests: knitr,
rmarkdown,
codetools
Example what happens when codetools is not installed:
* using R version 4.3.1 (2023-06-16)
* using platform: x86_64-pc-linux-gnu (64-bit)
...* checking re-building of vignette outputs ... ERROR
