Decode Multi-Select Variables

Decodes multi-select coded variables by mapping coded values to their corresponding meanings within bracketed strings.

Usage

decode_multi_select(x, code, meaning)

Arguments

x

Character vector of multi-select coded values. Each element should be in the format "[CODE1,CODE2]" or "[CODE1|CODE2]"

code

Character vector of coded values for mapping

meaning

Character vector of corresponding decoded meanings

Value

Character vector with decoded values. Multi-select values maintain bracketed format with decoded meanings separated by pipes.

Details

This function processes multi-select data where each observation may contain multiple coded values separated by commas or pipes within brackets. It replaces coded values with their decoded meanings while preserving the multi-select structure. All separators are normalized to pipes for downstream uniformity.

Examples

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

# Decode multi-select variables
# decoded <- decode_multi_select(
#   x = c("[A1,B2]", "[C3]", "[A1|B2|C3]"),
#   code = codes,
#   meaning = meanings
# )
# Result: c("[Option A|Option B]", "[Option C]", "[Option A|Option B|Option C]")
} # }
