Add documentation for pp*_data() companion functions #435
Description
Summary
bayesplot exports a *_data() companion for many of its plotting functions (e.g., ppc_error_data(), ppc_ribbon_data(), ppc_scatter_data(), etc.).
Currently, however, these functions lack documentation or usage instructions within the bayesplot package.
Proposed Changes
- Documentation: Create or expand documentation for all
*_data()functions. - Usage Instructions/Vignette: Provide a vignette or a section in existing documentation that demonstrates practical use cases for these functions.
