Check encoding issues in meta data

check_meta_encoding.Rd

This function checks the meta data of a GADSdat object for encoding issues, such as the presence of special characters (e.g., "Umlaute" or other non-ASCII characters). Encoding problems in meta data (e.g., variable labels, value labels) can lead to inconsistencies and issues when working with data across systems that expect clean encoding.

Usage

check_meta_encoding(GADSdat)

Arguments

GADSdat

A GADSdat object containing the data to be checked for meta data encoding issues.

Value

A data.frame that reports the variables and labels with encoding issues:

  • "varName": The name of the variable with encoding issues (if applicable).

  • "value": The problematic value (if applicable).

  • "GADSdat_varLabel": The variable label with the detected encoding issue.

  • "GADSdat_valLabel": The value label with the detected encoding issue.

If no issues are found, the function returns an empty data.frame.

Examples

# Example usage:
# Load example GADSdat object
GADSdat <- eatGADS::import_spss(system.file("extdata", "example_data2.sav", package = "eatFDZ"))

# Check for encoding issues in meta data
meta_encoding_issues <- check_meta_encoding(GADSdat)

# Print the result
print(meta_encoding_issues)
#>   varName GADSdat_varLabel value GADSdat_valLabel
#> 1 ID_name                ä    NA             <NA>
#> 2  school             <NA>     5     Förderschule
