We are pleased to announce that chronosphere v.0.2.2. is now on CRAN! This is only a minor update in which some bugs were fixed and minor features added/changed.
The following updates were made in chronosphere 0.2.2 (2020-02-17):
1. dataindex() function changed to datasets() The dataindex() function has now been deprecated in favour of datasets() to access list of datasets that are now available on the package. We thought that “datasets” was more intuitive than “dataindex”, hence the change.
