The dfcheck package was created to speed-up the boring and important step of checking the databases that user send us during the methodology consultations. Most of the time, we receive Excel files on the XLSX format. We open them using the openxlsx package, and we hope we could do some analysis on this data. But during the analysis, we detect always the same errors :
The problem is we need a minimum of structuration in the table to be able to give them to our statistic software. We previously tried to give to our users some guidelines to give us perfect data that should be directly processed using, for example, vartors. This improves the quality of the table, but errors are more insidious and cost us a lot of time to check and correct.
The main aim of the dfcheck package is to detect and repport the maximum of possible errors, before performing the statistical analysis.
