Structural data set errors in data frames

A summary of all variables and observational units that vary in number or name from the expected. Duplicates are also reported. The higher the number or percentage of mismatch or duplicates, the lower the data quality.
Note: elements represent study variables; records are observational units; counts refer to the total number, whereas sets check the actual names of the elements or records.

Note: elements represent study variables; records are observational units; counts refer to the total number, whereas sets check the actual names of the elements or records.
