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.
