Description

brms provides the helpful functions get_prior() and set_prior() to allow inspection and setting of priors

Could you kindly provide analogous functions for inspecting and setting initial values?

Contributor guide

Research direction
Examine the implementation of get prior and set prior in the brms source code to understand the pattern. Then investigate how initial values are handled internally (e.g., in the stanfit object) and design analogous functions get initial and set initial that allow users to inspect and set initial values for model parameters.
