Apologies to anyone trying to install reproducible, NetLogoR, and any SpaDES packages from CRAN. We had one of our dependencies (reproducible) temporarily archived, but we are in the process of submitting a fixed version, which should restore the other packages.
In the meantime, installing the GitHub versions of reproducible, followed by any other packages should get you back to a working version.
remotes::install_github("PredictiveEcology/reproducible")
remotes::install_github("PredictiveEcology/SpaDES.core")
