Check for the existence of character variables

check_character_vars.Rd

This function identifies all character variables in a GADSdat object and counts the number of unique values in each of those variables. Character variables are often of particular interest as they may contain free text or other non-standardized inputs that require additional review or processing.

Usage

check_character_vars(GADSdat)

Arguments

GADSdat

A GADSdat object containing the data to be checked.

Value

A data.frame with the following columns:

  • varName: The name of the character variable.

  • nUniqueValues: The number of unique values in the character variable.

If no character variables exist, 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 character variables and count unique values
character_vars_report <- check_character_vars(GADSdat)

# Print the report
print(character_vars_report)
#>   varName nUniqueValues
#> 1      ID            11
#> 2 ID_name            11
#> 3   infoß            10
#> 4 subjfav             8
