Apply SRTR factor labels to a data frame

Converts coded variables in an SRTR dataset into human-readable factors using the SRTR data dictionary and associated format tables.

Usage

apply_srtr_factors(df, file_key = NULL, verbose = FALSE)

Arguments

df

A data frame loaded from an SRTR SAF file.

file_key

Optional. The dataset name (e.g., "CAND_KIPA", "TX_KI"). If not provided, the function will use a file_key attribute or object name.

verbose

Logical. If TRUE, print each variable being labeled.

Value

A data frame with factor levels applied to coded variables.

Details

If file_key is not explicitly provided, the function will first check for a file_key attribute on the data frame (e.g., from load_srtr_file()). If not found, it will attempt to infer it from the object name.

Examples

if (FALSE) { # \dontrun{
# Explicit file_key
df <- read_sas("TX_KI.sas7bdat")
df <- apply_srtr_factors(df, file_key = "TX_KI", verbose = TRUE)

# Implicit file_key from attribute (if loaded via load_srtr_file)
df <- load_srtr_file("TX_KI")
df <- apply_srtr_factors(df)

# Fallback to object name inference
TX_KI <- read_sas("TX_KI.sas7bdat")
TX_KI <- apply_srtr_factors(TX_KI)
} # }
