Install specific data version

[shirdekel]

I understand that we can test for a particular data version using assert_data_version() and I know that I can install a particular reference/tag in a package from Github using, for instance, devtools::install_github("ropensci/DataPackageR@v0.1.1"). Is there a recommended way to install a particular data version of a data package from the installation? In other words, what happens after assert_data_version() fails? Where/how can the user find the relevant data version?

Ideally, your data package development would be under version control (e.g., git). In that case, to find an earlier version of your data package, you would do a git checkout of an earlier commit or tag to access an earlier version of your data package.
