Can get snapshots from https://mran.microsoft.com/documents/rro/reproducibility
# from https://resources.rstudio.com/webinars/time-travel-r
R.home()
```bash
cd /opt/R/3.6.0/lib/R
cat etc/Rprofile.site
```
# Add to Rprofile.site
local({
print("Setting frozen repo at data snapshot 123")
options(repos = c(CRAN = "https://...123"))
})
