Flag a column with no observed values

All values are NA (or, for text, blank/whitespace-only). Such a column usually means a variable that never recorded anything or an export artifact, and it is invisible to data_check_constant() which strips NAs.

Usage

data_check_empty(x)

Arguments

x

a vector

Value

list(problem, message, values)

Author
