We are pleased to announce that chronosphere v.0.3.0. is now on CRAN! This constitutes a major update to users to use
chronosphere in R 4.x.x, along with major updates to the
fetch function and some more variables added.
The following updates were made in chronosphere 0.3.0 (2020-06-15):
chronosphere 0.3.0 (2020-06-15) currently offers the following new features:
1. Changes to the
datasets() function gained the `
greetings arguments. The default setting of the function only downloads the list of datasets (dat) and variables (var). Setting the ‘dat’ argument to a character entry will download the list of all archives from that dataset. Setting the master argument to
master=TRUE will download a list of all archives, which is expected to be very long in the near future. The argument
greetings=TRUE will display a reminder that additional versions and resolutions are available.
2. Changes to the
- The downloaded objects now have chronosphere attributes. These record the accession information used previously, which allows the repetition of function call, if necessary - including changes.
fetch()can return the function call, using
call=TRUE. This can be either an expression or a terminal message, depending on the settings of
fetch()can be used with an already downloaded the chronosphere-object to either redownload it, or get its download function call.
fetch()can be used to return multiple variables from the same dataset. These will be concatenated into a list, unless they are RasterArrays, in which case
fetch()will try to
datasets("paleomap") # contains 3 variables fetch("paleomap")
3. the extent() method of the RasterArray class is now available
4. the server log
log.csv is only checked once per session.
5. New datasets available:
- Marine Ecoregions of the World
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. We appreciate any feedback.
