You need to give details what exactly gets you into trouble and about your use case, since any advice would be conditional on making assumptions about that. It is usually a bad a idea to have a function working on a hardcoded full filename. You will thank yourself later if you at least make it argument to your function(s). It can have for default value the one that is currently hardcoded.
Please note that your use case does not seem inherently related to staged installation. "Hardcoded" in the context of staged installation does not refer to any hardcoded path but to those paths that contain the temporary installation directory. Such paths can be obtained, for example, with calls to system.path(), as illustrated by Tomas.

I understand there is an opt out, but still want to know. here's the blog post: https://developer.r-project.org/Blog/public/2019/02/14/staged-install/ I have several packages which look like that: 1. large messy dataset stored on disk as `filename`, maybe a csv. 2. R package has a function `clean(filename)` which reads the data and brings it into useable form 3. R package does analysis 4. R package exports results `filename` is hard coded. What is the proper way to do this instead? Should I store the inital raw data inside the R package in `/inst`? These things are typically very large, so I like to decouple the raw data from the package (easier to share). thanks for any suggestions!
