is_data_dict_shape.RdTests if the input object has adequate structure to work with functions involving data dictionary shaping. This function mainly helps validate input within other functions of the package but could be used to check if an object is valid for use in a function.
is_data_dict_shape(object)A potential data dictionary structure to be evaluated.
A logical.
A data dictionary contains the list of variables in a dataset and metadata
about the variables and can be associated with a dataset. A data dictionary
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.
For a better assessment, please use data_dict_evaluate().
