[R-pkg-devel] implications of staged install for data processing packages

[Florian Oswald]

Hi all

I ran into trouble with the changes starting to come in with R3.6 stemming
from the new staged installation, which checks and errors on hard coded
paths in R code. 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!
