Details

If warnings are found, the function attempts to fix them and explains what it has done in the warning messages. If an error is found, checking stops and a NULL data frame is returned. The error is described in the error messages.

Value

A list containing

• df The loaded data frame, NULL if errors are present.

• warning A list of strings describing the errors that ocurred but could be fixed or that do not prevent the execution of the program.

• error A list of strings describing the errors that occurred that made it impossible to return a valid data frame. If this list is not empty, then the data frame item will be null.
