[R] Reproducibility Between Local and Remote Computer with R

[stephen sefick]

Caveat, I have only skimmed this email thread, so please forgive me if I
have missed something.

Are you able to use Renv, packrat, docker, or anaconda? Your compute
environments are very different.
Kindest regards,

Stephen Sefick
