Usage
data_clean_sosci(data, remove.na.levels = TRUE, remove.na.numbers = TRUE)

remove.na.levels |
Remove residual values from factor columns.
Either a character vector with residual values or TRUE to use defaults in VLKR_NA_LEVELS.
You can also define or disable residual levels by setting the global option vlkr.na.levels
(e.g. |
remove.na.numbers |

Either a numeric vector with residual values or TRUE to use defaults in VLKR_NA_NUMBERS.
