If your package is in github at https://github.com/julaiti/MSPC , it looks like
there is no inst or extdata folder in that repository.
Maybe it has not yet been added/committed/pushed to git?
Note that everything _under_ inst gets installed when you install the package,
but the inst directory itself goes away.
If in your package source you have the following structure:
inst/extdata/
inst/foo.txt
In the installed package you end up with:
extdata/
foo.txt
