chronosphere v.0.2.0 is now on CRAN!
We’re excited to announce that chronosphere 0.2.0 is now available on CRAN! You can install it with:
chronosphere was developed to facilitate the spatio-temporal analyses of deep time palaeoenvironment/palaeoecological research by serving as a gateway to data and tools usually used by paleontologists.
chronosphere 0.2.0 (2019-12-16) currently offers the following features:
- access to various datasets (use

This is a beta version. Much of the functionality is not yet available/perfect and data access is restricted to publicly available datasets only. Issues and bugreports should go to the GitHub repo issue tracker.
