Load a fit from a

Description

Reads a portable .fitrx archive written by [ferx_save_fit](ferx_save_fit.qmd)(or by the ferx-core Rust CLI’s --output flag) and reconstructs a ferx_fit-classed list. The returned object is structurally compatible with one returned by [ferx_fit](ferx_fit.qmd) for the fields covered by the cross-language schema, plus any R-specific fields the writer preserved under r_extras.

Usage

ferx_load_fit(path)

Arguments

• path: Path to a .fitrx file.

Details

To call [ferx_predict](ferx_predict.qmd) on a loaded fit, the embedded model source can be re-parsed through the existing pipeline.
