Is it possible to use RRO without checkpoint package?

Question

Revolution R Open (RRO) is distributed with checkpoint package to improve the reproducibility of package references. However, some users might not care about reproducibility but really cares about the performance enhancement RRO provides.

Is it possible to use RRO without checkpoint package and its functionality?

Answer 1

Yes, according to Revolution Analytics, you simply have to:

1. Update the .Rprofile to point to a different snapshot date: options(repos = c(CRAN = "https://mran.revolutionanalytics.com/snapshot/YYYY-MM-DD"))
2. Or, set the default repository to a standard CRAN mirror that refreshes daily, for example: options(repos = c(CRAN = "https://cran.revolutionanalytics.com"))

This allows you to get the most recent packages (link).
