chronosphere v0.2.2 on CRAN!

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.

head(datasets())

2. IPCC AR6 colour palettes added

In an attempt to keep the visualisation of environmental variables standard, we decided to adopt the IPCC palettes.

showPal()

ipccLine and ipccRCP are discrete colours for line graphs, with the ipccRCP representing the different climate scenarios

ipccRCP()

3. mapplot() bug fixed

In previous versions, a bug in the mapplot() function resetted the coordinates, thus not allowing to add other attributes to the plots, e.g. points. This has now been fixed.

Enjoy!
