Check and validate a file name

This function checks the validity of a file name, ensuring that it does not contain special characters (e.g., Umlaute) or spaces. File names with problematic encoding or formatting are flagged, as these issues may cause errors when processing files in different systems or environments.

Usage

check_file_name(path)

Arguments

path

A character string specifying the file path to be checked.

Value

This function returns an error if any issues are detected with the file name (e.g., special characters or spaces). If the file name is valid, no output is returned.

Examples

# Example of a valid file name
valid_path <- system.file("extdata", "example_data2.sav", package = "eatFDZ")
check_file_name(valid_path)

# Example of an invalid file name (this will throw an error)
invalid_path <- "invalid file name.sav"
check_file_name(invalid_path)
#> Error in check_file_name(invalid_path): File name contains special characters or spaces.
