Get the ice mask for a dataset, either for the whole series or for specific time points.


get_ice_mask(time_bp = NULL, dataset)



time slices in years before present (negative values represent time before present, positive values time in the future). This parameter can be a vector of times (the slices need to exist in the dataset), a list with a min and max element setting the range of values, or left to NULL to retrieve all time steps. To check which slices are available, you can use get_time_bp_steps().


string defining dataset to be downloaded (a list of possible values can be obtained with list_available_datasets()). This function will not work on custom datasets.
