Trace the runtime path of one call

Runs a call while temporarily instrumenting its entry function, first-level internal helpers, and S3 dispatch boundaries discovered in its static call tree. The trace is deliberately shallow: only instrumented R functions can be observed, and everything else is reported as unresolved rather than inferred.

Usage

trace_call(expr)

Arguments

expr

An unevaluated function call.

Value

An object of class insider_trace containing the original call, observed path and dispatch, the returned_class, captured conditions, and honest unresolved limitations.
