Restore renv lock file without redownloading packages

If you haven't already seen it, Using renv with Docker • renv may be helpful.

Also, I'm getting an error in the primary package I'm trying to run

library('Seurat')
Error: package or namespace load failed for ‘Seurat’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/root/project/renv/library/R-4.0/x86_64-pc-linux-gnu/stringi/libs/stringi.so':
  libicui18n.so.66: cannot open shared object file: No such file or directory

It was running fine from the cache before I did isolate() and copied the library to the docker container.

You likely need to install the requisite system library (libicu) on your container. Or, if you did install that library, then the issue is most likely that the version used in your container differs from your host machine.

Interesting, I would have thought renv::restore() would have configured the .libPaths() correctly.

renv::restore() doesn't change the library paths; it only installs packages from a lockfile into the requested library paths. Changing the active library paths for the session is a separate step.
