eelbrain.pipeline.LabelVar

class eelbrain.pipeline.LabelVar(source, codes, default=True, session=None)

Variable assigning labels to values

Parameters:

source (str) – Variable supplying the values (e.g., "trigger").
codes (Dict[str | float | Tuple[str, ...] | Tuple[float, ...], str | float]) – Mapping values in source to values in the new variable. The type of the values determines whether the output is a Factor (str values) or a Var (numerical values).
default (bool | str | float) – Label for values not in codes. By default, this is '' for categorial and 0 for numerical output. Set to False to pass through unlabeled input values.
session (str) – Only apply the variable to events from this session.
