Companions to use_dataset() for inspecting and resetting the session's
default dataset.
Value
get_dataset() returns the default data frame (error if none is set);
has_dataset() returns a logical; clear_dataset() returns TRUE
invisibly; dataset_vars() returns a character vector of column names.
Details
has_dataset() is the safe way to check before calling get_dataset(), which
errors when nothing is set. clear_dataset() removes the default so that
subsequent calls require an explicit data again – useful at the end of a
script or between analyses of different datasets.
