v0.4 specification API

Build and validate normalized mock_spec objects using direct helpers or composable variable constructors.

mock_spec(): Create a MockData specification
mock_continuous(): Create a direct continuous mock-data specification
mock_categorical(): Create a direct categorical mock-data specification
mock_date(): Create a direct date mock-data specification
mock_spec_continuous(): Create a continuous variable specification
mock_spec_categorical(): Create a categorical variable specification
mock_spec_date(): Create a date variable specification
is_mock_spec(): Check whether an object is a MockData specification
validate_mock_spec(): Validate a MockData specification
mock_spec_model_hints: Model hints for MockData specifications

v0.4 adapters and generation pipeline

Convert recodeflow metadata into mock_spec objects, generate baseline data, and apply post-processing diagnostics.

mock_spec_from_recodeflow(): Convert recodeflow metadata to a MockData specification
generate_mock_data_native(): Generate mock data with the native backend
generate_mock_data_simstudy(): Generate mock data with the optional simstudy backend
postprocess_mock_data(): Apply mock_spec post-processing rules

Main generation functions

Generate categorical, continuous, date, and survival variables. Use create_mock_data() for batch generation or individual functions for fine-grained control.

create_cat_var(): Create categorical variable for MockData
create_con_var(): Create continuous variable for MockData
create_date_var(): Create date variable for MockData
create_survival_dates(): Create paired survival dates for cohort studies
create_wide_survival_data(): Create wide survival data for cohort studies
create_mock_data(): Create mock data from configuration files

Configuration

Read and validate v0.2 configuration files. Import existing recodeflow metadata or create new configurations for mock data generation workflows.

read_mock_data_config(): Read and validate MockData configuration file defining variable specifications for mock data generation
read_mock_data_config_details(): Read and validate MockData configuration details file containing distribution parameters and category proportions
validate_mock_data_config(): Validate MockData configuration against schema requirements including required columns and unique identifiers
validate_mock_data_config_details(): Validate MockData configuration details against schema requirements including proportion sums and parameter completeness
validate_mockdata_metadata(): Validate MockData Extension Fields
import_from_recodeflow(): Import and convert recodeflow variables and variable details metadata files to MockData configuration format

Utilities for metadata processing, proportions, type coercion, and data quality. Support main generation functions or use directly for custom workflows.

get_variable_details(): Get variable details for specific variable
extract_proportions(): Extract proportions from details subset
extract_distribution_params(): Extract distribution parameters from details
sample_with_proportions(): Sample with proportions
apply_missing_codes(): Apply missing codes to values
apply_rtype_defaults(): Apply rType defaults to variable details
add_garbage(): Add garbage specifications to variables data frame
apply_garbage(): Apply garbage data from variables.csv
has_garbage(): Check if garbage is specified
make_garbage(): Make garbage
generate_garbage_values(): Generate garbage values
print(<mockdata_validation_result>): Print MockData Validation Results
get_variables_by_role(): Get variables by role
get_enabled_variables(): Get enabled variables
identify_derived_vars(): Identify derived variables using recodeflow patterns
get_raw_var_dependencies(): Extract raw variable dependencies from derived variable metadata
get_cycle_variables(): Get list of variables used in a specific database/cycle
get_raw_variables(): Get list of unique raw variables for a database/cycle

Parsers

Parse recodeflow notation for variable specifications and range syntax. Extract structured information from metadata for mock data generation.

parse_range_notation(): Parse range notation from variable_details
parse_variable_start(): Parse variableStart field to extract raw variable name
