Check for null and legacy no-data symbols

Source: R/check_general_null.R
check_general_null.Rd

Checks for null-like values (such as "NULL", "NA", and similar) in the data and metadata files, and for legacy no-data symbols (such as "N/A", ".", "..") in the data file.

Usage

check_general_null(data, meta, verbose = FALSE, stop_on_error = FALSE)

Arguments

data

A data frame of the data file

meta

A data frame of the metadata file

verbose

logical, if TRUE prints feedback messages to console for every test, if FALSE run silently

stop_on_error

logical, if TRUE will stop with an error if the result is "FAIL", and will throw genuine warning if result is "WARNING"

Value

a single row data frame

Details

Null-like symbols cause a failure; finding legacy no-data symbols produces a warning. The GSS provides guidance on the accepted symbols to use for representing missing or suppressed data.
