Write an rproject.toml file compatible with rv (https://github.com/A2-ai/rv)
Source:R/utils-toml.R
write_rproject_toml.RdDependencies are pinned by commit SHA, not by tag: the DESCRIPTION version
recorded in the manifest does not match the repos' git tags (tags carry a
v prefix, and .9000 dev versions have no tag at all), so tag pins can
never resolve. The SHA is the same reproducibility anchor manifest.csv
records.
