Check variable names for encoding issues and dots

check_var_names.Rd

This function checks whether variable names in a GADSdat object contain specific formatting issues, focusing on:

  • Encoding problems: Variables with non-ASCII characters, such as "Umlaute" or other special characters.

  • The presence of dots (".") in variable names.

Usage

check_var_names(GADSdat)

Arguments

GADSdat

A GADSdat object containing the data whose variable names are to be checked.

Value

A data.frame containing variable names that failed the checks. If all variable names meet the requirements, the function returns an empty data.frame.

Details

These checks help detect and report variable naming issues that may cause compatibility problems with certain tools or systems (e.g., Stata or databases with strict naming conventions).

Examples

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

# Check for problematic variable names
problematic_var_names <- check_var_names(GADSdat)

# Print the result
print(problematic_var_names)#'
#>   varName
#> 1   infoß
