Convert Factor Code to Label

Source: R/subgroup_consistency_helpers.R
FS_labels.Rd

Converts q-indexed codes to human-readable labels using the confs_labels mapping. Supports both full format ("q1.1", "q3.0") and short format ("q1", "q3"). Handles vector input via recursion.

Usage

FS_labels(Qsg, confs_labels)

Arguments

Qsg

Character. Factor code in format "q<index>.<action>" or "q<index>". For the full format, action 0 = NOT (complement), action 1 = IN (member). Short format defaults to action 1. Can also be a character vector for vectorized input.

confs_labels

Character vector. Labels for each factor, indexed by factor number.

Value

Character. Human-readable label wrapped in braces, e.g., "{age <= 50}" or "!{age <= 50}" for complement. Returns the original code if no match is found.

Examples

if (FALSE) { # \dontrun{
labels <- c("age <= 50", "tumor size <= 20", "nodes <= 3")
FS_labels("q1.1", labels)
FS_labels("q1.0", labels)
FS_labels("q2", labels)
FS_labels(c("q1", "q3"), labels)
} # }
