Loads and validates model configuration files, preparing the pipeline for execution. This function reads the model export file, variables file, and model steps file, and preloads all transformation parameter files into a cached model object.
Arguments
- model_export
A file path (character) to a model export CSV file. The model export must contain columns 'fileType' and 'filePath' that specify the locations of the variables and model-steps files. The directory containing the model export file is used as the root directory for resolving relative file paths found within the model-steps file.
Value
A model object (list) containing:
- root_dir
The root directory used for resolving file paths (derived from the model export file location)
- model_export
The model export data frame
- variables
The variables data frame
- model_steps
The model steps data frame
- predictor_variables
Character vector of predictor variable names
- files
Named list of cached file contents
