Decode Single-Select Variables

Decodes single-select coded variables by mapping coded values to their corresponding meanings.

Usage

decode_single_select(variable, code, meaning)

Arguments

variable

Character vector of coded values to be decoded

code

Character vector of coded values for mapping

meaning

Character vector of corresponding decoded meanings

Value

Character vector with decoded values. Mapped values are replaced with their meanings, unmapped values are preserved as-is.

Details

This function performs exact matching of coded values against a lookup table and replaces coded values with their decoded meanings. Values that don't match any code are preserved as-is.

Examples

if (FALSE) { # \dontrun{
# Create mapping
codes <- c("A1", "B2", "C3")
meanings <- c("Option A", "Option B", "Option C")

# Decode single-select variables
# decoded <- decode_single_select(
#   variable = c("A1", "B2", "A1", "UNKNOWN"),
#   code = codes,
#   meaning = meanings
# )
# Result: c("Option A", "Option B", "Option A", "UNKNOWN")
} # }
