pastclim 1.2: an R package to easily access and use paleoclimatic reconstructions
Ecography, First published: 05 January 2023 https://doi.org/10.1111/ecog.06481
Here is a list of what is new compared to the preprint:
- pastclim is now on CRAN: https://cran.r-project.org/web/packages/pastclim/index.html;
- We have added functions to crop based on an extent or a mask, and to randomly sample points across space and/or time;
- We added a cheatsheet summarising the main functions;
- A new vignette shows how to work with custom data and how to add them to the package in order for them to be available for all users.
Here is a table summarising the functions used in the package
| Download the data | |
| get_data_path() | Retrieve the path in which pastclim automatically stores the data |
| set_data_path() | Store the data in a custom path |
| download_dataset() | Download a whole dataset (all variables available) |
| get_vars_for_dataset() Download variables of choice for a given dataset | Download variables of choice for a given dataset |
| get_downloaded_datasets() | Summary of the downloaded variables |
| get_time_steps() | List of time steps available in a given dataset |
| Get climate for locations or regions | |
| location_slice() | Get the climate for given locations (by coordinates and age) |
| location_series() | Get time series of the climate for given locations |
| region_slice() | get the climate for a given region in a given time step |
| sample_region_slice() | sample a given number of points from the climate of a region |
| region_series() | get the time series of the climate for a given region |
| sample_region_series() | sample a given series of points from the time series of a region |
| Working with biomes and ice sheets | |
| get_biome_classes() | legend of the ‘biome’ categorical variable, when available |
| get_ice_mask() | get a mask with the extent of the ice sheets for a given time step |
| get_land_mask() | get a mask with the extent of the land masses for a given time step |
| Vignettes | |
