These utilities standardize survival status indicators so that downstream metrics always receive the conventional coding (0 = censored, 1 = event). The functions are intentionally unexported and are used across multiple internal modules. Normalize survival status coding to 0/1 representation
fastml_normalize_survival_status(status_vec, reference_length = NULL)A list with two elements: `status`, the recoded numeric vector, and `recoded`, a logical flag indicating whether a non-standard encoding was detected.
A vector containing survival status information. May be numeric, logical, factor, or character.
Optional integer specifying the desired length of the returned vector. When `status_vec` is `NULL`, this value controls the length of the output (defaulting to 0 when not supplied).
This helper attempts to coerce a status vector into a numeric format where 0 represents censoring and 1 represents the event indicator. It accepts a variety of common encodings such as 1/2, logical values, factors, or character labels. When the supplied values deviate from the canonical coding, the function records that a recode was performed so callers can communicate this to the user (once).
