Apply SRTR variable labels to a data frame

Adds human-readable variable labels to an SRTR dataset using the SRTR data dictionary.

Usage

apply_srtr_varlabels(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 the file was loaded via the load_srtr_file function, this argument should be unnecessary.

verbose

Logical. If TRUE, print each variable being labeled.

Value

A data frame with variable labels applied.

Details

If file_key is not explicitly provided, the function will first check for a file_key attribute on the data frame. 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_varlabels(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_varlabels(df)

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