Arguments

A list of data frame(s) representing metadata to be evaluated. |
Details
A data dictionary contains the list of variables in a dataset and metadata

object is a list of data frame(s) named 'Variables' (required) and
'Categories' (if any). To be usable in any function, the data frame
'Variables' must contain at least the name column, with all unique and
non-missing entries, and the data frame 'Categories' must contain at least
the variable and name columns, with unique combination of
variable and name.
Value
A data frame providing categorical variables that has issues within a data dictionary.
